Maintain alkalinity between 3.0 and 3.75 meq\/liter (8.4 and 10.5 dKH) by testing daily and adjusting dose accordingly. Depending on the degree of calcification occurring in the aquarium, dose may have to be significantly increased over our recommended starting dose. Never add more than 1 ml. per gallon of each component in a 24 hour period, and never allow pH to rise above 8.45.
