12 best silver algaecides

Silver algaecides are chemical compounds containing silver ions (Ag+) that are used to control and prevent algae growth in swimming pools, hot tubs, and other water features. Algae are simple, non-flowering plants that can grow in water environments and cause water discoloration, slippery surfaces, and foul odors.Silver algaecides work by disrupting the algae's cellular processes, preventing their growth and reproduction.

Here are some key points about silver algaecides and their usage in pools and water features:

  1. Algae Control: Silver algaecides are effective against a wide range of algae species, including green, yellow, and black algae. They are commonly used in conjunction with other pool sanitizers, such as chlorine, to maintain clear and algae-free water.

  2. Mode of Action: Silver ions attack the enzymes and proteins in algae cells, disrupting their metabolic processes. This disruption prevents algae from carrying out essential functions, leading to their death.

  3. Residual Effect: Silver algaecides can provide residual protection against algae growth, meaning they remain active in the water for an extended period. This residual effect helps prevent the recurrence of algae blooms.

  4. Dosage and Application: The dosage of silver algaecides varies based on the size of the pool or water feature and the severity of algae infestation. It is essential to follow the manufacturer's instructions for the correct dosage and application method.

  5. Compatibility: Silver algaecides are generally compatible with other pool chemicals, but it's crucial to check compatibility guidelines provided by the manufacturer. Using incompatible chemicals together can lead to ineffective treatment or even hazardous reactions.

  6. Prevention: Regular use of silver algaecides, along with proper pool maintenance practices like adequate filtration, pH balance, and water circulation, can help prevent algae growth in the first place.

  7. Safety: While silver algaecides are effective, it's essential to handle them with care. Users should wear appropriate protective gear, follow safety instructions, and store the chemicals in a cool, dry place away from other incompatible substances.

  8. Regulations: Different regions may have regulations regarding the use of silver algaecides and other pool chemicals. It's important for pool owners and operators to be aware of and comply with local regulations.

Remember, always follow the specific instructions provided by the manufacturer of the silver algaecide product you are using for the best results and safety.

User questions & answers

Question: Will this product kill existing algae? Tired of trying different products to control the yellow alage need help
Answer: This product is an algaecide or biocide and is not meant to take the place of your chlorination product. I have a 35,000 gal pool and was able to stop "shocking" my pool using this product. The manufacturers web site will give you the proper solution rate for your application. I have gone three years without "shocking" and algae free.
Question: Will my PH balance be affected with the use of No Mor Problems? I use a lot of PH Plus in order to keep the PH balanced and I don't want it lowered
Answer: Yes it can. We’ve been using it for about 4 years. It’s fantastic!
Question: Does the water turn green when applied
Answer: There are no ingredients listed on the bottle. It is sold by Applied Biochemists, an Arch Chemicals Inc. business in Alpharetta, GA. Their customer support phone # is 1-800-455-4311.
Question: I have a 10,000 gal. pool and i use chlorine tabs (about 3 per week). any suggestions as to how many ounces of no mor i should use per week
Answer: It's unfortunate that the maker of this product hasn't a time limitation to swim after a treatment. My experience is that the product turns your water brown for a time and you don't want to go in anyway. But my filter system, Pentair filter canisters, clears the water up in about six to eight hours. I may add that this product cleared up my black algae in a couple of days.

User questions & answers

Question: Can you use this in vinyl lined in ground pools
Answer: my Florida pool has a Diamond Brite finish. This product did absolutely nothing to the few spots of black algae. Hand scrubbing and then rubbibg with a chlorine tab was how I deleted the algae.
Question: It just says to apply, does that mean while the skimmer/filter is running? Or should it be turned off when I apply
Answer: This product works! Pool professional secret. I have 6000 gallon pool. To get rid of algae, use 2 tabs and 4 oz of product plus a pound of granular chlorine. Putting in some yellow out in is good to. You will treat again in a about 4 days. Run your pump for st least 8 hours. The no mo problems supercharges the chlorine. You can maintain same way but only use yellow out occasionally v
Question: we drained our pool due to black algae. Can we simply scrub this on the walls? It has been empty for 3 weeks and we want to treat it and refill
Answer: I am using much less pH plus and never have to use clarifier since starting No Mor Problems last year. SW Florida is inundated with acid rain in summer, so it's a real help in keeping the pool balanced.
Question: Will this work on a pebble - tech pool surface
Answer: No way as a matter of fact it will remove any green tint you may have from any alggee build up.

User questions & answers

Question: is the poolrx unit refillable each year
Answer: No... You replace it each year. They have a booster that you add after 6 months, but then each year you replace it.
Question: I placed a pool rx mineral unit in my pool two weeks ago. prior to adding it i had 0 copper now my reading shows .4. any one else have this issue
Answer: I really don't think you should worry about that reading. It has minerals in it so it is bound to show something. I put this in on June 17th in my 27,000 gallon pool and have not added one bag of shock or any algeacides even one time this entire Summer. It has been a miracle. It is so hot here in Texas and I am usually scrubbing my pool and adding chemicals all Summer. I have done absolutely nothing to my pool at all other than adding chlorine to the automatic chlorinator. I do know that you are supposed to removed the cartridge if you are adding extra chemicals to the pool
Question: Can you use this with a copper ionizer
Answer: I would not- We have a 27,000 gallon pool and one of the main activate ingredients is 47% + or - a few is copper. You'll create more problems down the road with high copper levels. We put one in near the pump in April and it last until late Aug for us. We buy another one to replace that one just to be on the safe side. It really depends on the usage and what area you live in. We are in FL and its gets high usage. We have the chlorine dialed down to the lowest setting and we add 1 pound of granulated chlorine every week to week and a half depending on how heavy the rain is. Otherwise this is one of the best items we found for the pool that reduces the chemicals used and its worked well for us as some of the people using it has sensitive skin. No issues with skin problems for us with this PoolRX. Also they make a refill for this its almost the same as the new model so we end up buying the new one. A helpful hint for disposal. Once the life is out of the unit and you removed it, put it on solid ground and step on it. The plastic will separate and the metal inside will be loose. You can take all three parts and toss it into you recycling can.
Question: How do you know when it needs to be replaced? We’ve only had ours in for 3 months and we’ve got an alge issue again. Is that the ‘sign’ to replace it
Answer: Carolyn- Assuming your pool water is in balance to the following parameters: Chlorine 0.5 - 1.0 (ppm) pH 7.2 - 7.8 Alk 80 - 120 TDS 0 - 5000 Calcium Hardness 200 - 500 Cyanuric 10 - 80 If you are using the correct size unit for your pool (30K gallons or less) and are running your pump at least 6-8 hours per day then algae growth in the pool would indicate there is not enough of the PoolRx minerals reaming in your pool. If your pool is 20K gallons or less you will need to add 1 PoolRx Booster #102001 at this point. If your pool is between 20-40K gallons, you will need to add 2 PoolRx Boosters at this point. PoolRx is not a “Time Released” product. All the minerals will dissolve out of the unit within a few hours of install. A PoolRx unit is made of 2 parts: 1. Alloy treated cylinder in the middle of your blue or black unit is used to re-ionize the PoolRX minerals every time the two make contact. The cylinder portion of the system has a useful life of 12 MONTHS IN THE WATER. After 12 month in the chlorinated water, the alloy coating on the cylinder will be degraded to the point that it will no longer effectively re-charge the minerals. 2. PoolRx minerals these minerals come packed inside the cylinder of a Blue or Black unit or can be purchased separately as a Booster. Whether purchased as a part of a PoolRX unit or as Booster the minerals are the exact same formula and will do the exact same thing. These minerals completely dissolve into solution within a few hours of being placed in your skimmer or pump basket and form a residual throughout the pool water for up to 6 months. Over the 6 month period you will lose these minerals via algae kill and splash out. In order to keep the PoolRx minerals active for up to 6 months, you must also have the PoolRx cylinder in the water. Without making contact with the cylinder, the minerals will lose their effectiveness within 2-4 weeks of install. To treat your pool for 12 month period: 1. Install PoolRX Blue or Black unit (based on Pool Size) 2. Approx 6 months later add the Booster (keeping the Blue or Black unit in your Pool) 3. Approx 6 months after Booster install remove the PoolRx Blue or Black unit and replace with a new one beginning the 12 month cycle all over again. How are Minerals lost? PoolRx minerals are lost through algae kill, splash out back washing and filter cleaning. The more these factors happen, the more extreme the conditions, the shorter the lifespan of the minerals. How do I know when to add more minerals? PoolRx uses proprietary chelating agents that protect the minerals from falling out of solution. Because of this, the PoolRx minerals cannot be tested for in the water by your typical reagent test equipment. You will know you need more minerals based on these factors: 1. Time: It’s been 4-6 months since you first installed PoolRx. 2. Your chlorine demand goes back up to where it was prior to installing PoolRx. 3. Your water is cloudy or you start to see algae. Note: Because a small amount of minerals are still working in the water you will notice a gradual change over about a two week period. This gives you plenty of time to add a booster or new PoolRx unit.
Question: can you use it to close your pool
Answer: Yes!
Question: my pool is approximatly 50 % well water 10,000 gallons, what might happen if I use this product
Answer: Ours is all well water, and it worked well for us.
Question: What can i use to clear out dead algae
Answer: It depends if your filter is clean, but I will assume you backwash at least once a week for a couple minutes and rinse for about 30 seconds. Do the following: 1. put in the recommended dosage of algecide on the bottle. There is two recommendations on all algecide bottles for a preventive or maintenance dose, if you see it, it is maintenance requiring a higher dosage. Fill up your pool with tap water till it is above the top of the skimmer. Leave the pool filter overnight for 24 hours, next day. Turn off your pool pump, put it in Waste position, turn on the pump, remove your skimmer basket, and hook up your pool cleaning hose to the skimmer pipe attached to your pole and scrub vacuum. I am in the above ground pool doing all this maintenance the dead algae and other debris is being sucked out and the bigger stuff is collected in your pool pump basket. The dead algae and smaller particles do not go in the sand tank, they are be flushed out in your yard or wherever your out valve is directed (I have a spray cannon so it waters my lawn at the same time and kills the grass where it lands from the chlorine (LOL). You need to move very slowly a small step at a time so not to stir up the bottom until you finish the entire pool. Secure the power and put the pump in the closed position, remove the pump filter basket and clean it out the basket with a garden hose till it is spotless, and put it back in the pump and secure the top. Remove the pool vacuum and hose from the skimmer and the pool, and put the clean basket back in there. Next go to the pool pump and place it in the backwash position, turn on the pump for about 2-3 minutes or until the site glass shows clear looking water, then shut off the pump, move to the rinse position for 30-60 seconds and shut the pool pump off, turn to the filter position, and turn the pump back on. If the water level is not at half line, add water, also add quick dissolve shock directly to the skimmer. Wait 24 hours and check the pool and it should be clear, but may have more dead algae or dirt on the bottom. This time you can just remove the skimmer basket and hook up the vacuum hose and repeat the cleaning process which will collect the larger stuff in the pool pump basket and the algae will go to the pump, but you can move a bit quicker. When done, disconnect the vacuum and hose and put the skimmer basket back in, shut off the pump and if larger debris was in the pool clean out the pump basket as previously done and put it all back. Then move the valve to Backwash for 2 minutes, rinse for only 30 seconds, and back to filter after shutting the pool off for each position change. Again top off the water to the half way mark and add a little quick dissolve again to directly to the skimmer. PS: The main algae growth source is usually in ladders doing into the pool, so they need to be removed and washed with a strong Clorox-water solution and hosed off and allowed to dry. Algae needs two sources for growth. UVA/UVB Light and high temperature that is above 78 degrees which is why we do not have algae problems in the colder weather. I use a pool pump and elevate the water up in the air about 10-15 feet to cool the water over night and I live in the swamps of Louisiana. LOL
Question: Can you use with vinyl liner
Answer: yes I use this on a vinyl pool liner

In The Swim Super Pool Algaecide

In The Swim Super Pool Algaecide is a concentrated, non-foaming formula, allowing the use of smaller amounts which makes it easier to measure. Super pool algaecide is fast acting so it saves time and money. In the Swim Super Pool Algaecide can apply as a treatment or as a maintenance product. Works on many types of algae. Can be applied to in or above ground pools.

Before adding In The Swim Super Pool Algaecide, make sure to brush your pool and clean or backwash your filter. Empty skimmer and pump baskets. Turn on the main circulation pump. Super chlorinate according to water volume and interior type. This will build a chlorine residual.

Pour the recommended dosage into a chemical safe container. Mix with 9 parts of pool or hose water. Pour the diluted mixture around the perimeter of the pool. Safe to swim immediately.

Pool Care and Maintenance

It is important to maintain your pool/spa to keep it clean and healthy all year round. Good habits, such as cleaning your filter or emptying your skimmer basket, will ensure that your investment is protected for years to come. But most importantly, you and your family will be able to enjoy the swimming pool or spa each season.

Water Testing

Testing the water weekly or bi-weekly, depending on use and outside variables, helps keep your pool/spa water healthy. Utilizing a DPD or OTO reagent-based water test kit, test strips, or digital testing will help you monitor the pool or spa water chemistry.

Adjusting and Balancing

Adjusting and balancing your pool or spa water chemistry ensures that you will get the most out of the swimming season. The benefit of having good pH and Alkalinity levels is that it will increase the ability of your main sanitizer to kill bacteria. Balanced pool water chemistry will also reduce chemical and maintenance costs. Balanced pH and alkalinity help prevent corrosion and scale formation on the interior pool surface and surrounding equipment.

Sanitizing

There are many different types of sanitizers used in various pool and spa environments. Clean and healthy water starts by establishing a proper residual chlorine level with shock or concentrated granular chlorine. The most common way to maintain a proper chlorine level is by using trichlor chlorine tablets in either a floater or chemical feeder. Applying these steps to your normal maintenance plan will ensure the elimination of non-living organic contaminants, bacteria, micro organisms, and algae making your water safe to enjoy.

Pool Fun and Safety

Now that the water is properly balanced and sanitized, it’s time to get in there and have some fun! We recommend enhancing your outdoor living environment with games, floats or loungers, toys, and accessories. Get creative!

Safety is of the utmost importance, and there are many ways to help make your pool/spa safer. Having a life ring buoy, a shepherd's hook, depth markers, coast guard-approved life preservers, door and water alarms and having your local aquatic environment safety regulations on-hand will ensure a fun and safe environment for your family.

Treatment

Even after all your preparation, sometimes life happens and your pool or spa can get away from you. In those moments, we need to start back from the beginning with testing of the water. Now that you have a clear idea of the current readings, your next steps will depend on the type of symptoms your water is presenting. This may include an issue such as algae (green, yellow, black, etc.), cloudiness, living organics, debris, and other water conditions.

PoolRx Pool Unit #101066 6 Month Algaecide Treats 20k - 30k gallons

PoolRx eliminates existing algae fast and prevents algae from coming back. The chelated minerals free up low levels of chlorine to be more productive in the water, providing amazing clarity. The minerals dissolve out of the unit completely and immediately to form a stable residual throughout the entire body of water. As the minerals pass over the PoolRx unit during circulation, they are rejuvenated to last longer. The minerals are used up through algae kill, back washing, splash out and filter cleanings. For longer season, larger pools, extreme conditions or green pools, you can add PoolRx booster minerals when needed. Replace the PoolRx unit at the beginning of each season for best results. PoolRx is ideal to use with Chlorine, Salt, UV or Ozone systems. Supporting any size body of water, PoolRx is perfect for both Residential and Commercial use.

User questions & answers

Question: Directions for use, step 1: "add a chlorine shock per use directions and run pump for one hour." do i need another product to use this product
Answer: I don’t know what size pool you have but it is good practice to shock (over chlorinate) every 3 months. Your pool supply company or Google can help. The reason you shock before clarifier is to kill algae first.
Question: Can I use this in our coleman above ground pool
Answer: We have an above ground pool that we use it on. Not a Coleman pool, it's a much older pool that we have had more than 15 years. The last liner replacement was three years ago and we've used this product on our liner without any noticable damage from this treatment. Hope this information helpful.
Question: Is this safe for saltwater pools
Answer: Yeah, It's just shock. Saltwater pools disinfect the same as any other pool it's just that the chlorine comes from salt in the water being broken down into Chlorine and Sodium by the saltwater element in the piping.
Question: My pool water is clear but I’m having a hard time killing the allege that is on the wall. Will this take care of that

Answer: I cannot imagine that it wouldn't be. But to be alcertain I would call a local pool supply store. I can also say that this brand is the best brand I have used so far in 3 years of owning a pool. Take that for what it's worth. I have only tried 2 other brands.
Question: Can this product be used in and around my dock in a lake? Wondering what to use to safely kill algae? THanks
Answer: No. It would flow away and dilute and not work like you think. It may get you fined (or worse) if you pour it in a lake. Stay legal ( Oh, and wear your mask.)
Question: Ok to use in pools with well water
Answer: Yes. I have used it for years and have a well with hard water but no iron. Not sure if iron makes a difference.
Question: is this a copper free based algaecide
Answer: It is classified as "metallic free" so I should be copper free

User questions & answers

Question: does it turn the water BLUE,,, that is what I wont in my pool,,,Blue water
Answer: it clears the water of any cloudiness. it does not turn the water blue. pool water will always reflect the color of your liner.
Question: Will this work without shocking first
Answer: Yes
Question: Exactly what chemicals are in this product? Do I use it in addition to shock, muriatic acid, algecide.... or instead of
Answer: This is not a product that replaces ANY pool chemical treatment. You still need your chlorine or other sanitizer, muriatic acid, CYA, Borax, algaecide, shock, etc. as usual. This enhances your usual maintenance chemicals. It does a great job of what I call clumping up small dust/dirt particles making it easier for the filter to remove them. It will not “turn you water blue,” but it does make the water crystal clear, and makes it sparkle. If you happen to have a liner with lots of blue in the pattern, it will make the water “appear” to be bluer, but all it does is remove fine particles, & makes the water crystal clear. I use it once a week, and dose after heavy rains. I’ve used it for 20 years, have tried others, but always come back to this.
Question: I have an Intex Metal Frame Pool with a Saltwater Pump and Filter System. Will this product work with that type of set up
Answer: Yes it stated on the bottle that it will work salt, and all types of filters/pumps.

User questions & answers

Question: Would this be useful to remove light particles from concrete driveway
Answer: I would think you need to have water since this can probably damage your pool surface. It does say on the bottle not to concentrate in just one area and that the ph of water has to be 7.2-7.8 in order for this product to work. From what I read, there is no way to actually get rid of black algae forever. I kinda grows deeper and deeper into the pool walls if left untreated for a while. Even if you use algaecide, it will take care of whatever it can, but the roots will still be left not visible to the naked eye. It starts growing back as soon as the chemistry in the pool is off again and doesn't get adjusted right away.

User questions & answers

Question: Does this product work on Simply Salt System
Answer: I have a saltwater system and this works really well with it it just took a little bit longer to clear out all the alge .
Question: can you use if had to treat water for iron,, we have iron stains removed and water balanced but are now having issues with algae even after shocking
Answer: I have used this product for several years, and it does a great job, but it does a much better job if you combine this along with the addition of Borax to your pool. If you add Borax, raise your Borate levels to around 50-80, and use this product, you will not have any problems with any type of algae growth. If you have small dogs that drink the pool water, it is best to keep the Borates between 30-50, but no higher.
Question: How long do you need to wait to go swimming after adding the Seaclear
Answer: I can't recall that there was any required wait time but I would add to the pool water in the evening and circulate overnight. This algaecide is so worth the money and will last three months pretty much to the day it was first added.
Question: I have a fifteen to twenty thousand gallon pool will I need two bottles? I have tried expensive products and just want one that works. My friend on face book recommended this as a great product that works
Answer: My pool is 18,000 gallons, and I tried this product. The first two weeks the pool looked great. A slight drop in chlorine left me with mustard algae. This product will work if you keep your chlorine at the correct level, but so will the aqua chem 20% algaecide, which costs less than 10% of the SeaKlear when you consider that the maintenance level is only 6 ounces. There is no product on the market that will keep algae out of your pool if you don't maintain your chlorine level. Here in Florida, mustard algae is persistent, and is in the air, so we fight that every year. It is much cheaper to buy a mustard algae killer and shock the pool every week during the swimming season. One product I use is a phosphate remover. Most algaes require phosphates to grow and thrive. Anything you can do to keep the phosphate level low will help. Any pool place can test for phosphates. We do not have our pool covered, and have lots of trees. Leaves get in the pool and increase the phosphate levels, so I use the phosphate remover for that purpose. The one I have is made by SeaKlear.
Question: I have three crane pumps in my fountain. Is this product safe for the pumps? They are a mix of metals. Brass, stainless etc
Answer: Safe
Question: Does this product stain cement
Answer: It absolutely does not stain cement. My fountain is cement. When you first put FounTec into the fountain the water turns the color of Caribbean ocean water. Quite beautiful. But this fade in a couple of days. Even the blue water that cascades out of the fountain doesn't stain the cement. I have used this product for years (15) and reorder every year. I highly recommend it. Does not harm the birds that drink out of my fountain.
Question: What kind of non chlorine product should be used to eliminate existing algae growth before using the fountec as a maintenance product
Answer: It depends upon the amount of algae you're dealing with, realizing that chlorine-based products are far more effective than non-chlorine (with names often starting with "oxy ...". This article explains the pluses and minuses of both sanitizers: https://blog.poolcenter.com/article.aspx?articleid=6631
Question: Does this eat away the finish/paints of a poly-resin fountain
Answer: Has not affected my natural rock & concrete waterfall. No effect on two in-ground black vinyl koi ponds either. Unsure of painted surfaces ... depends on the paint & how applied.
