Aquarium pH Regulators

Good water quality is an essential factor in maintaining new or established aquariums. Poor water quality stresses fish, which leaves them susceptible to disease and possibly death and a stable pH level is one of these components needed for maintaining a healthy environment. The pH scale measures pH levels from 1 to 14. 7 is the neutral point in the pH scale, where the water is neither acid nor alkaline. As the scale goes down, water becomes more acidic, and as the scale goes up, water becomes more alkaline.

Frequently Asked Questions

Regulating pH can be accomplished by using certain substrates, conducting proper water changes as well as the use of pH buffers.

It depends on the type of aquarium and the species you are housing. For example, a safe pH for marine/saltwater is 8.2 to 8.4, whereas freshwater pH ranges from 6.8 for fish like goldfish to 7.0-7.5 for community freshwater aquatic life and cichlid/discus prefer a pH of 7.6 to 8.0.

While substrates like aragonite are able to help stabilize or raise pH, silicate sands should not affect pH in a tank.
