BIONIX Freshwater Master Test Kit (200 Test) | ph Ammonia Nitrite & Nitrate Test kit for Aquarium.

I’m using this water test kit in my Caridina shrimp tank, where water parameters are absolutely key, and it has been very reliable. It covers pH, ammonia, nitrate, and nitrite—everything needed for proper aquarium monitoring. The accuracy is great, and what makes it even better is the step-by-step video guides on their YouTube channel, which make testing very easy. The price is very reasonable compared to other brands, and considering the quality, it’s definitely worth it. I would absolutely prefer this kit over other brands for both value and ease of use.

Good product, budget friendly and accurate test results. Need to follow user manual to perform all tests and you can compare the results with the charts given in the booklet. Much cheaper than API MASTER TEST KIT, and value for money.

I am very happy with this test kit. It includes all the important tests needed for a freshwater aquarium, such as pH, ammonia, nitrite, and nitrate. I tested all of them, and the results were easy to understand and seemed accurate. The kit is well organised and provides everything required to regularly monitor water quality. The only small issue I faced was with a few of the reagent bottles. The caps were difficult to puncture, so the liquid didn't flow out easily at first. I would request the seller to improve this part of the packaging, as it would make the kit much more convenient to use. Other than that, it's an excellent product. I would definitely recommend it to anyone looking for a reliable freshwater aquarium test kit.

I'm incredibly impressed with the Bionex Master Water Test Kit. It's super easy to use, with clear instructions and charts. The accuracy is fantastic, giving me reliable results every time for all key parameters like ammonia, nitrite, nitrate and ph. This kit has made managing my aquarium water quality so much simpler and more effective. Highly recommended for any aquatic enthusiast.

Amazing test kit for this price!! Have rechecked with api test kit it’s pretty accurate, good job by bionix, the customer support is amazing, I had issue with nitrate reagent 2 and he rectified the issue immediately by sending a spare one, the only drawback i experienced was the smell, which they promised to rectify in coming months. Great product great service MUST BUY!!!

I recently purchased it, and found it is below standard. Our lab protocol is far better that than this product.

I have never expected that i will test the water of 150 gallon myself... 😃 Thanks to BIONIX who helped me over call aswell as shared corresponding YT videos for a better clarity and confidence. Finally, I think i have made a correct decision in buying this product over other competitors.

Dear Hobbyist, This is a good kit, All instructions are clearly mentioned and yields similar results on second testing as well, my tank conditions were perfect so I wasn't seeing any positive results, The packaging could be better and a stand for tubes would make this process much easier, Good one can go for it. Didn't test for caridina tanks or tanks with tannins. The reagents smell very strong, so keep em away from nose.
