Test Kits

In order for fish to thrive, water conditions in the aquarium need to be the same or very similar to those found in nature. These kits measure 5 of the most important aquariums conditions: pH, Nitrite, Nitrate, Carbonate and General Hardness.

Nutrafin's Calcium Test measures calcium in fresh and saltwater aquariums. Marine reef aquariums, especially those containing hard corals and strong growth of coralline algae, absorb calcium at a rapid rate, often requiring daily testing to ensure that th

Nutrafin's Nitrate Test (0.0 - 110.0 mg/L) measures nitrate in fresh and saltwater aquariums. Nitrate should be tested on a regular basis as an indicator of pollution in the aquarium and to determine if a water change is necessary.

Nutrafin's Phosphate (0.0 - 1.0 mg/L) Test measures phosphate in fresh and saltwater aquariums. Phosphate levels should be monitored weekly. High levels of phosphate, often the result of overfeeding or infrequent water changes, can contribute to unsightly

Nutrafin's Iron Test (0.0 - 1.0 mg/L) measures iron levels in fresh and saltwater aquariums. Iron must be carefully monitored and kept at a level that supports and maintains lush, planted aquariums. It is recommended to test iron with a frequency that wil

Nutrafin's Carbonate and General Hardness Test measures Carbonate Hardness (KH) and General Hardness (GH) in fresh and saltwater aquariums. Carbonate Hardness (KH) must be tested on a regular basis because it fluctuates over time and can negatively impact

Nutrafin's Nitrite Test (0.0 - 3.3 mg/L) measures the nitrite levels in fresh or saltwater aquariums. Nitrite should be tested on a weekly basis, as it is a toxic and potentially lethal nitrogen compound for fish.

Nutrafin?s pH High Range Test (7.4 - 8.6) measures pH levels in fresh and saltwater aquariums containing fish that prefer alkaline conditions, such as African Cichlids or marine fish. pH should be monitored regularly as it can directly affect the well-bei
