JBL ProAquaTest NH4 Ammonia & Refill

After losing a few fish earlier this year, I finally got serious about monitoring the nitrogen cycle. This test makes checking ammonium and ammonia levels clear and straightforward, even for a beginner. It’s given me peace of mind knowing my water’s biological balance is stable.

I test my water weekly and this ammonia kit gives clear, easy-to-read results every time. The refill option is perfect for keeping costs down, and it catches ammonia spikes before my fish get stressed. Exactly what I needed for peace of mind with my planted tank.

I was worried about my new tank cycling, but this test kit gives clear readings down to 0.2 mg/l, which helped me track the ammonia spike. The refill option is a nice money-saver since I'll need to test regularly.
