Co2 Permanent test kit is designed unit for attaching inside the aquarium which permanently displays the pH value or the CO2 content of the aquarium water.

The pH-level indicates the acidity of the water. The higher the pH-level, the less acid is in the water, the proportion of alkali is higher (the opposite of acids). The lower the pH-level, the more acid the water contains. In aquariums and ponds the following levels are desirable.

Community aquariums: pH: 6,5 – 7,5
Lake Malawi and Tanganyika aquariums: pH: 7,5-8,5
