Alkalinity Checker HI772 LED Lights GFO and Phosban can remainThe HI772 CheckerHC (Handheld Colorimeter) provides a simple, accurate, and cost effective way to measure alkalinity in degrees of carbonate hardness, commonly abbreviated as dKH. Critical to marine environments, alkalinity not only provides the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, but it also acts as a pH buffer against large changes in acidity. Designed as a more accurate alternative to chemical test
