[This review was collected as part of a promotion.] Best water kit i have used to date. Looked super intimidating at first because there is so much to it, but the directions made it so easy to follow. I am so impressed

[This review was collected as part of a promotion.] Big API fan as their products always work! Great fish tank test kit, it’s very nice to be able to test each thing you’re looking for individually versus doing a strip test I feel that this test is more accurate than a strip test. I low that tho lo comes in a nice container for storage and organization.

[This review was collected as part of a promotion.] API Freshwater Master Test Kit is very useful. It tests pH , High Range pH, AMMONIA NITRITE & NITRATE levels. The kit includes instructions on how to perform each test and how to interpret the results which is very helpful.

[This review was collected as part of a promotion.] Absolutely the best kit I've used when testing water. I love how long this kit is going to last with the amount of tests it can do. So I like that the money is worth it. Its super easy to use, just fill your water you want to test to the line, add the amount of drops the bottle (it shows on the front of each bottle the amount of drops is needed, which is super awesome, because I have lost the packaging before) or you can read the pamphlet, and the put it next to the test sheet. The results are super easy to read, you get the results immediately and know exactly whether you need to fix the water in your aquarium or pond (this has been beneficial for both) i like the box that it comes in, uts durable and holds everything perfectly. None of the vials were broke, and I appreciate there being 4, I found that super helpful. Overall I cant complain at all, its perfect. And I definitely recommend it.
