API Aquarium Water Check-Up Test Kit, 300 Tests - Accurately Test for Ammonia & Nitrite in Freshwater & Saltwater Aquariums

Ammonia and nitrite are the two most dangerous parameters for aquarium fish and the most immediately important thing to measure when starting an aquarium. Ammonia is the number one stressor and killer of tropical fish as it is released into an aquarium in the forms of uneaten food, decaying organic matter, and when fish release it through their gills, urine, and solid waste. Low levels of nitrite inhibit respiration and suppress the immune system, while high levels cause suffocation in fish. The API AQUARIUM WATER CHECK-UP KIT allows for measurement of both parameters using colorimetric testing for the most accurate results. We recommend that you take a few minutes each week to monitor your aquarium water quality levels and create a better underwater world for your fish.
