Using constant aeration in the tank can slightly elevate the pH levels.

The high volumes of oxygen continuously introduced into a system will drive down the carbon-dioxide levels, which causes pH to rise.

Crushed coral used as a substrate will naturally increase the pH without harming the fish..

Will high pH kill fish?

Tank or pond fish water with a high pH is highly basic or alkaline, and can chap or chemically burn a fish’s skin. Young fish are more sensitive to higher acidic water than adult fish. Fish water that has a pH of 5 is too acidic and will kill off fish eggs, they will not hatch.

How much vinegar do I put in my fish tank to lower pH?

The increase in carbon dioxide reduces the pH of the aquarium water. Experts at Reefkeeping Online Magazine recommend no more than 1mL of vinegar per gallon of water added to the sump or an area of high water-flow and few creatures, to allow proper dilution. This amount should lower the tank pH by about 0.3 points.
