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 and can be dipped directly into the aquarium testing all five elements with one strip - no need for separate vials or tubes. Simply compare to the highly precise colour chart provided to monitor the levels.
