What Causes Calcium Buildup In Fish Tanks?

pH Levels Of Above 7.5

Basic water naturally allows for calcium carbonate to precipitate as salts.

High concentrations of carbonate force more calcium ions to bind with carbonate, forming more precipitate on surfaces.

Bicarbonate Concentrations Of 120ppm and Above
