GUIDELINES:
Mix 1/8 to 2 teaspoons maximum per gallon of fresh water (preferably reverse osmosis or de-ionized water) in separate clean container. Shake/stir mixture vigorously. Let stand for several hours until visible layers appear. Layers should appear as follows (top to bottom): a white crust on top, a clear fluid, a milky white fluid, and a white precipitate will form on the bottom. Skim the upper crust layer off and discard. Draw off the clear liquid layer (this is the fluid you want) without disturbing the layers below. This clear layer should be added to the aquarium system very slowly. It is recommended to use a drip system as dosing should be on a continual basis and at the same rate to replace amount of water lost to evaporation. The KENT Marine AquaDose is the ideal drip dosing system. The bottom two milky white layers should also be discarded.
Different reef systems have different calcium needs. To determine the calcium usage of your system, monitor calcium demand by testing aquarium water daily for about a week and replacing the amount of calcium that is being used.
If you are having trouble maintaining calcium or buffer levels, check to see that the salt mix you are using contains natural seawater levels of magnesium. Magnesium is necessary and low levels result in poor calcium solubility and buffering.
