Daily fish tank maintenance

Stable tanks should show no detectable ammonia.

If ammonia is still present after a period of cycling,

  1. Wanda Russell –

    The test is very easy to use and gives clear results. I used it during the first week of setting up my tank and caught a high ammonia level early. I changed the water immediately and the fish stayed healthy. The color change is noticeable even at low concentrations.

  2. Joanne Hemmings –

    Great for monitoring new tanks. I tested every few days during cycling and noticed the ammonia dropped steadily. The instructions are clear and the test strips are reliable. Only slightly sensitive to background interference at very low levels.

  3. Rachel McDonald –

    Used it in a quarantine tank for a sick fish. The test detected a spike in ammonia quickly, which helped me take action before the fish got worse. Very effective and fast to read.
