Alkalinity, also referred to as carbonate hardness or buffering capacity, is essentially a means of quantifying the stability of pH in a solution, such as aquarium water. Maintaining the alkalinity in marine aquaria between 7 - 12 dKH (2.5 - 4.3 meq/L) will generally maintain pH within the desired range.
Determine alkalinity in aquarium with an accurate test kit prior to supplementing. Do not add this product directly to an aquarium without first diluting in water as directed.
Instructions and Guidelines:
Basic: Dissolve 2 grams (~_ 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, 500 g treats up to 5,000 US-gallons
Advanced: Create a stock solution by dissolving 20 grams (~5 teaspoons) of ALKALIN8.3-P in 8-fl. oz. of fresh water (preferably purified); each ml of the solution will increase the alkalinity in 1 US-gallon (3.785 L) of water by 0.36 dKH (0.13 meq/L). [Reference: Each g of ALKALIN8.3-P will increase the alkalinity in 1 US-gallon (3.785 L) of water by 6.8 dKH (2.5 meq/L).] If initial alkalinity in the aquarium is below 7 dKH (2.5 meq/L), add the stock solution at the maximum rate of 10 ml per 20 US-gallons daily until desired alkalinity is attained, then dose daily or weekly as needed (see below). Maintain the alkalinity within a range of +/-1 dKH. Once the desired alkalinity has been acquired, measure the alkalinity at the same time each day over a one-to-two-week period to determine required dosing rate. To determine the daily dosing rate (preferable to weekly dosing): estimate the volume of water in the entire aquarium system; divide the daily decrease in alkalinity by 0.36 when measuring dKH or by 0.13 when measuring meq/L; multiply this number by the volume of water (gallons) in the system to get the daily ml of stock solution required to maintain stable alkalinity.
Contains carbonate and bicarbonate salts; harmful if swallowed. If swallowed: give water, get medical attention. May cause eye or skin irritation. If in eyes, flush with water for 15 minutes, get medical attention. If on skin, wash thoroughly with water. Keep out of reach of children. Not for human consumption.
