## Description

A complex formula of pH buffers, designed to adjust alkalinity of saltwater and fresh water aquariums. Its use is necessary to counteract the pH fluctuations keeping the KH (Carbonate Hardness) to the requested level. Designed to increase KH while improving its long-term stability. A perfect additive to be used also in Balling Method in combination with Extra Calcium, Magnesium, and our line of Trace Elements. Use: add every other day or as needed to maintain the KH concentration within the correct range. It is suggested to create a stock solution by dissolving 10 grams (~2,5 teaspoons) of product in 0,2 lt (6,7 fl. oz.) of RO water; each ml of the solution will increase the KH concentration in 5 lt (1,32 US-gal) of water by 0.3 ppm.
