The API 5 in 1 Aquarium Test Strip is a quick and easy way to test the water in your aquarium for five different elements;
- pH levels (Acidity)
- KH ( Carbonate Hardness)
- GH ( General Hardness)
They can be used in both fresh and salt water aquariums to quickly let you know whether you need to treat the water.
Each box contains 25 test strips (5 of each test) and can be dipped directly into the aquarium - no need for separate vials or tubes. Simply compare to the colour chart provided to monitor the levels.
