Fritz RPM Elements Alkalinity Aquarium Water Treatment, 1-gal bottle

Adjustment Dosage: Begin by measuring the alkalinity of the aquarium water and determine how much you wish to increase it. Each ml of Pt 1 will increase the alkalinity in 1 US gallon (3.78 L) of water by 2.1 dKH (0.75 meq/ml). One teaspoon (5 ml) will raise 10 US gallons by 1.06 dKH (0.38 meq/L). Do not exceed 5 ml per 10 gallons daily, and always avoid an immediate +/* 0.2 change in pH. Routine Dosing: Once alkalinity has been adjusted to the desired level, recommended starting dose is 5 ml (1tsp) each of Pt 1 and Pt 2 per 20 gallons of aquarium water per day. Maintain alkalinity between 8-11 dKH (2.8-3.9 meq/L) 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 recommended starting dose.
