Instructions and Guidelines
Basic: Dissolve 2 grams (~½ teaspoon) of product per 20 US-gallons of aquarium water in 8-fl. oz. of fresh water; add every other day or as needed to maintain the alkalinity within a range of 7 - 12 dKH. When used in this fashion, 1,000 g treats up to 10,000 US-gallons (37,854 L).
Advanced: Determine the alkalinity in the aquarium using an accurate test kit before supplementing. Each g of Alkalin8.3-P will increase the alkalinity in 1 US-gallon (3.785 L) of water by 12 dKH (4.2 meq/L).]
EZ Calculations: For dKH: Multiply tank capacity in gallons x dKH increase desired x .089 = grams of product to add. Example to raise the alkalinity by 1.2 dKH in a 50 gallon tank the calculation is: 1.2 x 50 x 0.089 = 5.35 grams or 1 teaspoon. For meq/L: Multiply tank capacity in gallons x meq/L increase desired x .25 = grams of product to add. Example to raise the alkalinity by 0.5 meq/L in a 50 gallon tank the calculation is: 0.5 x 50 x 0.25 = 6.25 grams or 1.2 teaspoons.
