User questions & answers

Question:	What size brush for cleaning
Answer:	I do not know, order not for me
Question:	Can these be used to store Isopropyl Alcohol for on to go first aid kit? How big is the tube and is it fragile or strong enough for extended use
Answer:	I have noticed that the caps, while quite appropriate for water parameter test kits, would not be suitable for long-term storage of any liquid. They leak a bit.
Question:	What are the dimensions of the vial? Is there a cheaper alternative? 20 dollars seems like a lot for what we're getting
Answer:	yes there is cheaper alternatives. I just bought plastic and glass ones with the little caps. The API ones however have nicer caps. Have a marking where 5ml is (which takes out guesswork) The ones I bought have no such graduations. So Im back looking at these because I was cheap the first time around. Maybe we should split the box of 24. Like you I have no need for 24 tubes. I need about 6. Dont forget these are glass tubes too. Some of the reagents in the API test kit are caustic and they will react with plastic test tubes (somewhat) I dont know. The them being glass, the caps and the marking that say 5ml make this a perfect match. One of the local fish stores has these for 1 dollar per test tube. I might buy them there too. Hard to say.
Question:	What test tube rack would be best for these
Answer:	I built my own. If you want a cheap hack, get a block of styrofoam and press the top of an open test tube into it at intervals to get the outer diameter perfect. Then cut out the styrofoam to the best depth. Test tubes fit snugly.

Testing the Waters

In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even loss. Most common water quality parameters are Ammonia, Nitrite, Nitrate, and pH. All may vary over time and all are invisible to the eye which is why it is important to test weekly. Testing aquarium water weekly will aid in keeping your most important water parameters within the proper range for your aquarium. Choose from a wide range of API testing options, such as our popular FRESHWATER MASTER TEST KIT or 5-IN-1 TEST STRIPS, for accurate water evaluation. Regular testing will help you easily determine your aquarium conditions.

Your API Test Options

Choose the test method that works best for you. Whether you’re a bit pressed for time, or you prefer to measure your parameters on a more in-depth scale, or you only need to test one or two specific parameters, API has what you need!

Dip and Read

Product description

As we work to deliver an amazing product, it had been brought to our attention that some racks were impacted by a gluing issue. The racks have been redesigned to create more surface area for the adhesive to bind the hand-assembled parts - this we trust will take care of the gluing issue that afflicted some racks in the past.

• Will safely hold 6 test tubes - no more trying to use generic racks with holes too large!

• Compatible with both API and Tililly Concepts 5 ml aquarium test tubes (13mm diameter)

• Made of shatter-resistant acrylic; hand-assembled

• Rinse and dry your test tubes on the drying poles

• Complements all API freshwater and saltwater tests

• Please note: test tubes are NOT included in this offer.

We are aware that some customers would prefer longer drying posts, however, there were a few reasons we decided against this in the design phase:

With the racks being handmade, the poles are more prone to detaching/ breaking in transit through the e-commerce chain even when well-packaged (more packaging = more plastic waste as this product requires bubble bags).

Secondly, the tubes dry completely within 48 hours even if they touch the bottom of the rack as air does get through - and this is the conservative time it takes on very humid days when drying takes longer.

Please do not place rack inside a cupboard when drying test tubes.

User questions & answers

Question:	Mine arrived broken. Has everyone else’s test tube rack held up ok over time? Just wondering how durable it is
Answer:	The cloth is a professional polishing cloth designed to clean and polish the finest gold, silver or platinum jewelry and watches. It has approval and endorsement of many fine jewelers worldwide. Best cloth I have every used. Have not used for your specific need but would not hesitate to do so.

Product description

Keep your fish healthy and thriving by testing your aquarium water's GH levels regularly with this easy-to-use API GH & KH TEST KIT for freshwater aquariums. Testing water parameters weekly helps prevent invisible water problems that can be harmful to fish. Water hardness is a measure of the dissolved mineral content of water. There are two types: the general hardness (GH) and carbonate hardness (KH). When keeping freshwater fish and plants, the GH and the KH of aquarium water should match their natural habitat. The API GH & KH TEST KIT helps aquarists duplicate the natural habitat of their fish, as well as detect low KH levels, which can lead to rapid and wide pH shifts, stressing fish. API GH & KH TEST KIT contains KH test bottle, GH test bottle, instructions with color card, and two capped glass test tubes. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium.

User questions & answers

Question:	Which test kit do I need to test alkalinity
Answer:	KH measures akalinity
Question:	Ok, my Molly tank read : 12 drops of gh to turn color and 1 drop of kh to turn color. Does this seem suitable for mollies
Answer:	I always thought that particular test was a bit confusing as it has no color sample in which to judge the test color by. When you say it takes 12 drops to turn color ( Green ) how deep is the " color" Green ? Look at the colors indicated by the Ammonia test to get an idea on how deep a Green color you have. I have Endlers in a tank and my readings for that tank are just like yours. My Endlers are active, have a good appetite so I would say that your Molly's should be happy with those readings With that said, I would say that the PH is a bit more important than the GH&KH test. Mollies also like to munch on Algae and or Green Veges so provide some for their good health. They also like plants to hang out in, and to provide safety for the fry's.
Question:	When I did this, the water changed to a pale yellow or blue within one drop. Are you supposed to keep putting drops in until it is much darker
Answer:	Make sure you shake several times after after each drop. Bright yellow for KH not pale yellow. Green change for GH.
Question:	Can someone share instructions please? Mine got destroyed. Thank you
Answer:	Fill a test tube to the level line. Add one drop at a time and invert tube to mix after each drop. For KH (Carbonate Hardness), the test is complete when water changes from blue to yellow. For GH it is complete when water changes from orange to green. For both tests it is one drop per degree of hardness. So if the KH test takes 5 drops, your CO3 Hardness is 5 dKH. (Its also 17.9 ppm/per degree if you want to convert)

Product description

Most water problems are invisible to the eye. Quickly measure and modify the six aquarium levels that are most important to the health of your freshwater fish with the API FRESHWATER MASTER TEST KIT. To stay healthy and thrive, fish need properly balanced levels of ammonia, pH, high range pH, nitrite and nitrate. These levels can change rapidly and create harmful conditions when fish waste, uneaten food or other organic matter accumulate, or when untreated water is added. If left uncorrected, all of these can be harmful or even fatal to fish, with consequences such as reduction of oxygen, increase in stress and higher risk of disease. The API FRESHWATER MASTER TEST KIT measures these six parameters with scientific accuracy and provides professional results. It comes with four glass test tubes, a holding tray, test tube rack and computer calibrated, laminated color card. Just fill the test tubes, add the test drops and compare results to the color card. Then follow the recommendations on the card if action is required. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium.

User questions & answers

Question:	Can any of these tests be used for both saltwater and freshwater? I noticed a lot of the individually packaged tests say they can be used for both
Answer:	Api ammonia, nitrite and nitrate test kits can be used for both salt and fresh water aquariums, the liquid solutions are the same for salt and fresh. BUT the color cards that you use to compare your test to are slightly different. I have both fresh water and marine. The first time I bought these kits, I bought for saltwater and freshwater and never threw away the color cards. Now it doesn't matter if I get freshwater or saltwater test kits because I have both freshwater and saltwater cards.
Question:	Would this kit be a good one for my planted aquarium
Answer:	Yes, this is a good general water testing kit, unless you have plants that are very sensitive to water hardness. This kit does NOT include a water-hardness tester.
Question:	I'm a newbie. I have a betta in 10G tank and I'm told that I need to test the water always.Not sure if I should get this or get cheaper ones instead
Answer:	Frankly, with a 10G tank you should just be doing weekly water changes of at least 25-30%. You can't really "let things go" with a tank that size and it's unlikely that you would have ammonia spikes with such frequent water changes. I have a little 5.5 gallon with a couple of albino cory cats and I use a test strip every once in a blue moon, but the water is always fine because I do weekly changes. Am looking at this kit for my 125 gallon tank, but would bother for a tiny tank.
Question:	How many tests can be run with this kit
Answer:	About 120. Problem is that if you use the full set of products daily you will quickly run out of the ammonia test and the Nitrates tests (each with 2 bottles) because they take 8-10 drops each, compared to the Ph test which only takes 3 drops. I mainly test ammonia and nitrites so I've had to buy separate ammonia kits twice now because I ran out of fluid, while my high range ph bottle is nearly full. Also - Prime, AmGuard and other products convert Ammonia into harmless Ammonium however, it will still read as ammonia on your API kit - so it's basically lying to you. There are kits that will show you active ammonia and harmless ammonium and my API kit reads 8.0 ammonia but the other kit reads it as all harmless ammonium and zero active ammonia. You have do dose your tank with Prime every 48 hours or less to keep the ammonium from converting back to killer ammonia. This will keep happening until your tank finally converts the ammonium to nitrites. My 2 of my 4 well-cycled tanks somehow lost their cycling so that's not happening for those tanks yet.

Why be proactive with water treatments?

A natural pond has a constant supply of fresh water flowing into it, such as from a stream or spring. Water also flows out of a natural pond, taking fish waste and other toxins with it. This isn’t true for most garden ponds as they are closed systems. Garden ponds also tend to be much smaller than natural ponds, so they do not offer the amount of water per fish that you find in nature. For these reasons, water treatments are necessary to keep water conditions safe for both fish and plant life and for clearer water.

Following specific steps each season allows you to create a backyard retreat you’ll enjoy all year long! For more information about what’s needed each season, check out more below.

Spring Start Up - Get Your Pond Ready!

It's pond startup time! Whether filling a new pond or re-establishing an existing pond, following some simple steps at startup will yield benefits you’ll enjoy all season long. The 3 key steps that must be taken are making your tap water safe, activating the natural pond cycle, and maintaining sparkling clean water to boost fish and plant health. Once the water temperature reaches above 42⁰F, you’ll also want to start feeding your fish again. It is important to take care of all of your plants in the spring with API AQUATIC PLANT MEDIA and API AQUATIC PLANT FOOD TABLETS as they will be the key to success in most ponds! Lastly, monitor the water conditions in your pond with the API POND MASTER TEST KIT, an easy and accurate way to test 4 key water parameters including pH, ammonia, nitrite, and phosphate.

Summer - Provide Regular Care And Enjoy Your Pond

Summer is the time to sit back and enjoy all of your hard work! You’ll need to continue regular care for your pond that includes adding beneficial bacteria like API POND-ZYME and API POND ECOFIX. While everything looks great, you’ll want to closely monitor the water conditions so that you can protect the health of your pond including plants and fish. Algae grows in the presence of sunlight where there is excess nutrients in the pond water for the algae to feed on. API POND ALGAEFIX has been used for over 18 years to effectively control green water algae, string algae, and blanketweed without harming fish or plants. At this time it could be beneficial to do a partial water change, adding API POND STRESS COAT and API POND SALT and fertilizing your pond plants.

Autumn - Prepare For Winter

Performing a few simple steps in the autumn will prepare your fish and plants for the long, cold winter ahead and lay the foundation for a healthy start in the spring. We recommend removing excess organic matter (like leaves and grass clippings, for example) to reduce fish stress during the winter months. Use a net to remove as many leaves as possible. Routine addition of API POND ECOFIX or API POND-ZYME throughout the season promotes healthy water quality and reduces the amount of organic matter you need to remove at the end of the season. It is also important to perform a 25% water change, adding API POND STRESS COAT and API POND SALT to make the tap water safe and to replenish important electrolytes which aid fish during the stressful winter months.

Winter – Keep Pond Water Circulating

In cooler climates, when the water temperature drops, fish will naturally eat less than at warmer temperatures. Once the water temperature drops below 42⁰F, fish will cease eating and if they have been fed properly through the summer and autumn, they will have ample reserves to survive the rigors of winter. It is also important to ensure your pond has circulation to keep an open area on the ponds surface throughout the winter months to prevent the buildup of toxic gases which can accumulate from the decomposition of organic matter.

Answer:	10.25" x ~4.75" x ~2.75"The W and H are a little shorter than mentioned, but I was being lazy. I use this rack for holding test tubes for aquarium chemical level tests. Works pretty well for me. Kind flimsy if you don't put in the middle shelf. It's strong enough for me to carry it with one hand from one of the legs.The top of the first shelf is about .5" off the table. The top of the top shelf is 2.5" off the table.
Question:	Is this autoclavable
Answer:	I purchased this rack intending to use it for 15 cm tubes of beads, however I found it is not ideal for tubes that long. It will hold them, but they flop around a lot and this causes the "shelves" of the rack to start sliding out. A taller rack or one with shelves that were fixed in place would be better.
Question:	what is the dimensions , L X W X H
Answer:	No, these are plastic test tubes and cannot be boiled.
Question:	Would this be able to hold up a tube that's 15 cm long? I want to make sure the tubes I use arent too long
Answer:	No, they are not dishwasher safe. Pleas wash them by hand.
