Ammonia Test Strips

Ammonia: Is very harmful to fish and will cause stress, lower resistance to disease, damage gills and skin or even result in death.  Ammonia is a waste product excreted through the fish's skin and gills or through buildup of fish waste or decaying food.  In new aquariums, ammonia can rise to 6 ppm or more but will decrease as your biological filter becomes established, which can take a few weeks.  Readings should be kept to 0 ppm to ensure fish health.  Test for Ammonia weekly and more often for new aquariums.
