API Aquarium 5 in 1 Test Strips (Pack of 4) - pH, NO2, NO3, KH & GH
Water conditions in the aquarium need to be the same or very similar to those found in nature in order for fish to thrive and remain healthy, which is why it is vital to test aquarium water regularly and incorporate it into a part of routine aquarium maintenance.
Strips are very easy to use, simply dip into the water and read the scale.
This kit contains 4 test strips, and tests the following 5 parameters: pH, Nitrite, Nitrate, Carbonate Hardness and General Hardness.
Levels should be tested weekly to ensure they do not reach undesirable levels.
