Equipped with seven solution bottles, a laminated color card, and four capped test tubes, it provides precise, easy-to-use testing that helps prevent invisible water problems and fish loss. Trusted by aquarists for over 60 years, this kit is essential for weekly water quality monitoring and maintaining a thriving aquatic environment. ## 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 test tubes, a holding tray 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 almost 60 years API has developed premium solutions with proven and effective results for your family and ours. API offers a range of testing kits, water conditioners, and nutritionally superior food, because we’re dedicated to making a better underwater world.

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. **Q: 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.** A: 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. **Q: Would this kit be a good one for my planted aquarium?** A: 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. **Q: 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.** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I will buy it again *by on Reviewed in the United States July 4, 2026* Easy to understand the instructions. Comes in a portable case which is a perfect caddy to go from one aquarium to the next. No scent that I detected. The case is durable and has an easy storage system that holds each vile. The colors are easy to get a reading to match against and each bottle has a different color for color coded instructions. The helped me adjust my water parameters to better suit my tropical fish. Very effective. ### ⭐⭐⭐⭐⭐ Good *by on Reviewed in the United States August 8, 2026* This kit will last you a while, the material is good and it is very simple and easy to use. It doesn’t smell bad at all.The tubing is plastic, and I recommend handling with gentle care because you can rip off the lids if you mis treat it, but other than that the whole kit is good. The color comes out pretty precise, and the instruction manual tells you everything you need to do especially for people’s first time using it.Personally in the back of the book there are blank pages, and I like writing the date and the results every time I water test. Just a little tip! ### ⭐⭐⭐⭐⭐ Every aquarist should have this! *by on Reviewed in the United States March 23, 2026* This is a crucial need for EVERY aquarist out there. This kit is worth the time and money and it lasts me foreverrr. Will forever be buying refills. This kit is so beneficial in cycling your tank and checking for ACCURATE water parameters. It’s easy to use and I love feeling like a scientist when testing. Will forever recommend this product to those who need it. ## Frequently Bought Together - API FRESHWATER MASTER TEST KIT 800-Test Freshwater Aquarium Water Master Test Kit, White, Single, Multi-colored - PAIZOO Fish Tank Digital Thermometer Accurate LED Display to ±0.9°F Tank Thermometer Aquarium Temperature Measurement Suitable for Fish, Axolotl, Turtle or Aquatic - Tetra Water Cleaner Gravel Siphon for Aquariums, Easily Clean Freshwater Aquariums --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://belarus.desertcart.com/products/1627314-api-test-kits](https://belarus.desertcart.com/products/1627314-api-test-kits) --- *Product available on Desertcart Belarus* *Store origin: BY* *Last updated: 2026-08-27*
