API POND ALGAEFIX Algae Control

Algae growth can appear as “green water” blooms, "pea-green soup", filamentous algae on plants, or floating mats (blanket weed). Algae grows when there is an excessive amount of nutrients in the water, usually in spring prior to plant growth, and in the summer in direct sun.

API POND ALGAEFIX Algae Control works fast to control algae growth and keep ponds, water gardens and fountains clean and clear.

User questions & answers

Question:	Should i drain my pond & remove all the string algae & let it sit empty over a winter/snow/ice before i fill it again & add the green clean
Answer:	yes it is safe i have used it often
Question:	How much is needed for a gallon of water
Answer:	It is safe for fish and plants and when I used it I did not kill any frogs etc. I will say however that I have come to realize that usually when you have a lot of algae in the water it is only temporary. I no longer use these chemicals. The pond will usually balance itself.
Question:	Does this work well on the algae floating in the water as well as the string algae
Answer:	Thanks for your question. You'll want to dose your fountain every three days until the algae is controlled and then once every 5-7 days as maintenance. If you need more help you can call Pond & Garden Depot toll free at 1-866-305-5456

Where, when and how to use

GreenClean Granular Algaecide can be used with confidence in water gardens, ornamental ponds, fountains, irrigation ponds and other water features.

It is recommended to use this product at the first sign of algae growth. For best results, apply in the morning hours when the water is warm; sunlight and higher water temperatures accelerate GreenClean Granular’s activity.

Check the water’s pH levels before application; the pH should be between 6.8-7.8. Turn off any water circulation for 10-20 minutes when applying. Administer to affected areas and skim dead algae from the water’s surface to prevent future growth.

Why GreenClean Granular Algaecide?

GreenClean Granular Algaecide uses its unique and powerful chemistry to control algae blooms. Through the power of oxidation, its effects can be seen immediately. Formulated without the use of harsh chemicals, GreenClean Granular Algaecide leaves no residual and benefits the aquatic ecosystem by releasing vital oxygen into the water as it biodegrades.

User questions & answers

Question:	What pond size will it treat
Answer:	I have a water-filled quarry that's 200' x 100' x 100' deep and I only have to treat it with one bottle because the top of the water is where the algae and other organisms grow. In my situation, my estimations are for treating the top 4-feet of water, but as the liquid settles into the deeper water, it is also effective. I'm a chemical engineer, so I know hat the liquid only settles in the warm water on the top layer (thermocline). It works immediately to kill algae, so dramatically fast that everyone there when I first applied it was awed.
Question:	This was recommended by a local university ag agent for my small 50 gal. pond but the online info says not to use in small ponds. Any advice
Answer:	Thanks for your question. Draining the pond and removing the string algae will be a sure fire way to make sure you get rid of everything. However that defeats the purpose of using an algaecide. Greenclean starts killing algae on contact and can be mixed with your pond water. If you want more help you can call Pond & Garden Depot toll free at 1-866-305-5459.Cody H.Customer Service
Question:	Is it safe to use in a 800 gallon cattle tank? If so, how is it applied
Answer:	This is not a mix with water product its for lightly sprinkled over the affected area.
Question:	How much liquid would I need for a large pond about 50 foot diameter
Answer:	If you are referring to green water then this would not be your most effective treatment. If you are referring to huge chunks of floating string algae then this would destroy them very quickly once you sprinkle it on. However you should be aware that the dead algae mess will most likely continue to float for quite a while. Also, any time you use an algae killing product you definitely want to add a beneficial bacteria treatment. Otherwise the dead algae are not consumed and they become the food source for the next generation of algae. Graystone Industries 706-865-0220

User questions & answers

Question:	Can I use this on a galvanized stock tank pond
Answer:	I have had birds drink out of my pond after I put in the Aglaecide and did not see any harmful effects. But use as directed. I put in two doses too close together and several of my fish died.
Question:	On average how often do you use this product
Answer:	I have a 1/4 acre pond and I can get 5 treatments out of one gallon. Keep in mind, all I use it for is algie growth on the edges of the pond. Now for the good news, I have almost stop using it since started using pond dye. That stop the algie almost 100 percent if I make the pond very dark with the dye. Also, I found cirtine granuals to be more effective than the liquid. But, give the dye a thought and do some research on it. You may find it a better choice, I did. Saves a tone of $$ as well.
Question:	I have Japanese Trapdoor snail. Can I use this product
Answer:	I couldn't say what the risks are in using this Cutrine in small ponds. IF I still had my 100 gal. pond I would probably try a very weak solution of it. Be sure of the concentration shown on the label. Some jugs are a 9% copper and some are a 27% copper solution. That would make a big factor in your dilution rate. If it were me I would mix about 2 or 3 tablespoons into a gallon of water then add it to my pond then check for results in a few days. I would want plenty of circulation in that pond, too. It still may require scraping the algae from the sides.
Question:	Will Algaecide harm birds
Answer:	Yes, it's safe to drink, and it can be applied to water the water in the tank, but it has to be mixed with it first to disperse it before the cattle can ingest it. For questions like this one, call their tech support number. This product is used in water for fish farms because it does no harm. I've been using it since 1995 in my water-filled quarry where people swim and fish, and it works dramatically well.

Question:	Is this safe for a turtle pond
Answer:	It is safe for my goldfish and water lilies, but I don't have any snails. Sorry that I can't answer the question.

Answer:	Yes it will. It does a great job. I will be getting more. Plus you don't need to put much in. Only a few drops. Depending on the size of the fountain
Question:	Is this product for cats drinking out of fountain
Answer:	Yes it is. I was looking for a chemical that would be safe for a fountain that cats and birds occasionally drink from, and this does fit that bill. I see in this thread that there is quite some confusion about this topic, because the label says that it is a pesticide and lists warnings for human consumption while at the same time saying it is safe for pets and birds (but not most fish). In fact both are true - it is all about the quantities. Most of the things we consume are dangerous when consumed in pure form or large amounts. Large amounts of table salt are harmful, just like large amounts of chlorine which is typically added to our drinking water. In fact, even large amounts of completely purified and de-ionised water will kill you. That obviously does not mean that you should not drink water or eat anything with salt in it - it just means that an excess of anything can be bad. The active chemical in this algaecide is polyquat. Polyquat has been extensively studied and starts to show toxicity in various animals at ingested amounts of 0.5g-1g per kg body weight per day over an extended period of time. This product contains 30% polyquat, so for a child that weighs 20 pounds drinking in the order of a tablespoon per day directly out of the bottle would be likely to cause problems. This is why there is a warning on the label: if anyone would ingest a large amount directly from the bottle this could definitely be harmful. However if you use the product as directed, you actually add only one drop of the product per gallon of water. Even a tiny kitten that weighs 2 pounds would have to drink 30 gallons a day from that fountain to ingest enough of the chemical to get into the range of adverse effects. Obviously that is not very likely. It is possible that some subtle effects are not detected in studies, so it is typically recommended to stay well below the dose that would cause any issues, but as a kitten is unlikely to drink more than a cup it stays about 500x under the exposure limits. Finally: some chemicals can accumulate in the body and thereby long-term exposure to small quantities can still become dangerous over time. Retention of polyquat in the body is minimal, so this is not a real concern for this product. I hope that clarifies some of the confusion. source: https://pubchem.ncbi.nlm.nih.gov/compound/122130603#section=Top

User questions & answers

Question:	Will this effect trout or bass
Answer:	I treat my 100' x 200' x 4' deep quarry with 1 bottle of liquid Cutrine Plus that diluted, and I use a 1 gallon juicer to throw the mixture around initially, then it disperses itself throughout the whole quarry. I've seen algae react immediately on impact when I threw it in. I throw it in on one side of the quarry only and it spreads itself. The change is so dramatic that I've had swimmers over the decades willing to buy more for the quarry just to see the crystal-clear water. In 1994, I had a problem with red algae occurring, and didn't know how to treat it. I had the professor from Lehigh Univrsity and Muhlenberg College look at it and analysis it, but she had no solution to get rid of it. In my conversation with a man about selling me a tank with sand as a filter, he asked me why I didn't just use this product. I hadn't heard of it before, but he was correct. I called their tech department and followed through from there, and I've never been sorry. Cutrine Plus is tremendously effective and safe.
Question:	Can cutrine plus liquid be used in combination with nt max microbial digester to kill algae and then have the microbes clean up
Answer:	Kills algae .....I would say not safe for plants .....
Question:	Do u treat the entire pond or just were the algae is
Answer:	That's a great question ! There are no ingredients listed on the bottle. I am going to ask the seller myself.
Question:	Approximately how much to treat a 50' x 100' pond & how often? 1 to 4 1/2 feet deep
Answer:	My bird bath isn't 5 gallons either! It's only 1/4 of a gallon, so I put in about 10-12 drops. That's the best math I could come up with!

Question:	is it safe for fish
Answer:	This product is definitely safe for birds. I have been using it for about ten years to clean my pondless waterfall. It gets rid of the algae (it takes about a half day after turning back on my waterfall for the algae to dissolve) and it has not affected the many birds who drink from the waterfall.
Question:	Item weight 1 lb., Shipping weight 7.9 lbs. how much actual product? I cannot tell what I am buying
Answer:	Hello, this product contains the same active ingredient as Algae-fix but at a 6% (vs 5% for Algae-fix).

Question:	Does it expire? I'm debating getting the larger size
Answer:	Works in a day or 2. The algae doesn’t immediately disappear. It kills the algae, you will see it turn a less green color and then it gradually decomposes over time.
Question:	Is it safe for birds
Answer:	Depends upon the lot #. Keep the product in a sealed container and it will be good for many years to come.

User questions & answers

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:	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.
Question:	Does this product stain cement
Answer:	Yes. It's wonderful. I no longer remember it's instructions which I used to follow explicitly when we first got the pond. Then I found the pond care people simply sprinkling it everywhere without measureing and said it was perfectly safe. We have streams which get string algae. I turn off the water to them, sprinkle it all evenly with Ecoblast, let it sit for at least 30-45 minutes and turn them back on. If you aren't treating streams then you would turn off the skimmer so the water is still and then sprinkle the Ecoblast. It sinks to the bottom and debris floats to the top. After 30 minutes then turn the skimmer back on. Just be prepared to clean the skimmer in short order :)
Question:	What kind of non chlorine product should be used to eliminate existing algae growth before using the fountec as a maintenance product
Answer:	Hello, We apologize for the frequently confusing amazon listings. Most of the individual dealers listing this product have little control over what the ad actually says, but i can assure you that from Practical Garden Ponds this will be 7 pounds of product if you choose the 7 lb option of the three optional sizes.
Question:	Does this eat away the finish/paints of a poly-resin fountain
Answer:	Thanks for your question. There is a printed expiration date on this product and based on the answers to this question I'm guessing some sellers may try to sell product past that date. Our Ecoblast's printed expiration date isn't until May of 2020. It is worth noting that if kept dry this product will maintain effectiveness even past the printed expiration date.

User questions & answers

Question:	Can this be used in a galvanized metal fountain
Answer:	Don’t know, but my water has been crystal clear.
Question:	Is this OK for birds in a birdbath
Answer:	Safe
Question:	Will this help with lime build up from city tap water
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:	Will this distort the color of resin fountain
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 ...".

User questions & answers

Question:	How many drops do I put in my fountain that’s uses 1 1/2 gallons of water
Answer:	That is not it’s intended purpose. I’m sure you could use enough to do that but at much higher concentration than suggested. Moving water in fountain usually limits mosquito reproduction.
Question:	What is/are the active ingredient(s
Answer:	I used it in my galvanized metal fountain this summer and have had no problems.
Question:	Will it kill plants around the fountain
Answer:	I don’t think so. If it’s not safe for fish ponds, I can’t imagine that it would be for birds.
Question:	Does this kill mosquito eggs
Answer:	I do not have lime in my water. It is very alkaline it does help with algae.
