pH balance is a basic necessity for all aquatic life. Keeping the pH of your tank within the ideal limits by using the Aqua One pH ProPen will ensure the longevity of your aquatic pets. One of the major factors which determines good water quality is pH, which is the measure of acidity/ alkalinity in aquarium water. Neutral water has a pH of 7, Acidic water has a pH between 0 and 6.9 , Alkaline water has a pH between 7.1 - 14

Aqua One recommends these specific pH levels:

Common Tropical fish = 7.
Goldfish = 7.0
Common Cichlids such as angel fish can be kept at 6.5
African Cichlids 7.8 - 8.2
