API TEST KITS

Safe to use, good quality and has instructions. Size is great which means the kit lasts forever, it doesn’t smell. Easy to use with clear instructions. Brochure looks great and good material. Price beats all sellers.

This test kit is definitely accurate — I’ve used it side-by-side with other tests and it consistently gives clear, reliable readings. It covers everything I need for my freshwater tanks (ammonia, nitrite, nitrate, pH), and it’s saved me from some serious water parameter issues more than once. That said, the process isn’t exactly quick or convenient. You’ve got to measure out water into test tubes, shake bottles, time everything exactly, and match colors that sometimes look way too similar. It works, but it’s not something I look forward to doing, especially if I’m testing multiple tanks or running through every parameter at once. What I liked: - Very accurate and consistent results - Covers all the main water parameters - Plenty of tests per bottle - More reliable than strips or cheap alternatives What I disliked: - Takes a while to run a full round of tests - Color matching can be hard under certain lighting - Lots of little pieces to keep track of It’s a solid kit and does the job well — just be ready for a bit of a routine every time you use it. I keep using it because I trust the results, but I wouldn’t mind if they made the process a little more user-friendly.

I picked up the API Freshwater Master Test Kit when setting up my 6-gallon planted tank, and it’s been a huge upgrade over the test strips I started with. The strips were frustrating—hard to read, not very precise, and the gaps between values made it difficult to really understand what was going on in my tank. With this kit, the results feel much more accurate and consistent. I actually feel confident making adjustments based on the readings now. It’s also just a better overall experience. The process is straightforward, and there’s something oddly fun about it—it definitely gives off “mad chemist” vibes in the best way.

Amazing kit! It helps continuously check the water parameters in my tanks to keep my fish, shrimps, and snails healthy. It's a great value for your money. It's safe to use; however, if you get the product on your hand, it will stain, lol.

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.

Overall I do like this product. There's only one real issue I have with it, along with two minor issues. The first issue is the measurement line they tell you to fill to isn't actually at 5ml. It isn't a huge issue but I feel for tests that could affect the well being of people's fish it should be as accurate as possible. The instructions clearly state the line is supposed to be 5ml. I've run tests both at the line they provide as well as at 5ml measured with syringes. The results are pretty close but there is slight differences in results. The second issue is that the results can be a little difficult to read. It's definitely easier to read than other tests I've tried, but I do struggle sometimes if the color is between the faint green/yellow colors. Two ways to remedy this is to either put a white piece of paper behind the tube when reading results, or to just line the tube up over whatever test you're doing and see which color is closest that way. The last issue is that the tubes/caps are a little annoying to dry. I don't mind too much but I could see how some people might. I find the easiest way to dry it is to take a papertowel and twist it into a point and just shove it in the tube and turn it in a circle to dry it all. Then I just put it back in the container without the top on so it can air dry in case there's any leftover moisture. Other than those concerns I do think it's a pretty good product. I guess the last thing to say is that obviously the tubes are glass so be careful with them, I'd recommend only putting the tubes in their spots bottom down so you don't accidentally break the fragile top part.

Easy to follow directions a lot more accurate readings that the test strips. Happy with my purchase as I’m cycling me tank

I moved away from test strips and bought the API 800 Test Freshwater Master Kit. One of the best decisions I have made for my aquarium. Test strips may look convenient but once the container is opened and the strips are exposed to air the clock is ticking. Moisture and oxygen start degrading the reagents immediately. After about 30 days the accuracy drops off badly. At that point the readings are questionable and you may as well consider them unreliable. For something as important as water quality, that simply is not good enough. The API Freshwater Master Kit solves that problem completely. The reagents are stored in sealed bottles so they remain stable and accurate for a long time. Using it is straightforward. Fill the test tube with tank water to the line, add the correct number of drops from the bottle, cap the tube and shake. For nitrate there is a second bottle and a longer shake but it is still very simple. Wait the specified time, then compare the colour against the chart. That is it. What you get in return is far more reliable information. The colour changes are clearer and the scale is more precise than strips. You can properly track ammonia, nitrite, nitrate and pH rather than relying on vague strip colours that can be difficult to read. Each kit also lasts a very long time because you get a large number of tests from the bottles. It ends up being far better value than constantly replacing strips that degrade quickly. If you want accurate, repeatable readings and a clear picture of what is happening in your tank water, this kit is excellent. Simple to use, dependable and well worth the money. Highly recommended for any serious fish keeper. 🐟

Excellent Quality. Accurate test result. I recommend this product. Delivery recieved early

There is a reason why this test kit is considered the best amongst aquarists and fishkeepers. It is more on the pricey side and there are definitely more cost effectivr kits in the market. However, it very simple to use and the instructions are easy to follow. Highly recommend this kit for individuals starting out in the hobby as testing the water is essential for keeping your fish alive.
