R/O RECOMMENDATIONS: Use approximately ½ to 1 teaspoon per gallon of R/O or deionized   (purified) water. Exact measurement is not necessary because aragonite controls the ionic strength of the water. Shake or stir, then let settle for 10-20 minutes. Simply decant the clear water for top off water. Any left over or undissolved Aragamight™ Ocean Calcium can be used next time, just refill the container with R/O water. Add more Aragamight™ Ocean Calcium as needed Use every time you top off. One pound of Aragamight™ Ocean Calcium re-mineralizes over 300 gallons of R/O water.

Or ADD DIRECTLY TO AQUARIUM: In a clean Plastic or glass container, mix approximately 1 teaspoon aragaMIGHT™ Ocean Calcium with 2 cups of R/O or aquarium water. Stir or shake well, then add a tablespoon at a time to tank until aquarium water takes on a slight haze. The left over solution can be re-mixed and used later as needed. For best results, use daily. There is no risk of overdose.
