AquaLife Simple Science Calcium Reef Supplement Part B

-Raises calcium in reef aquarium

-Ionically Balanced Formula

-Formulated for Maximum Results AquaLife Simple Science Magnesium Reef Supplement Part A

-Raises magnesium in reef aquariums

-Ionically Balanced Formula

-Formulated for Maximum Results

Corals and many other reef invertebrates require a constant supply of both calcium and carbonate in order to construct their skeletons. AquaLife Ion-Balance A is the calcium component of our simple, two part system for reef tank maintenance. AquaLife Ion-Balance B is the carbonate component of our system. These two components are formulated to provide calcium and carbonate in ionically-balanced solutions made from high-purity ingredients.

Seawater is a complex mixture of many ions. One of these, magnesium, must be maintained at a concentration of 1290 to 1320 ppm (NSW = 1292 ppm at salinity of 35 ppt) when using any form of calcium and alkalinity supplementation. Otherwise, unwanted precipitation of calcium carbonate will make these ions unavailable to the invertebrates. Therefore, AquaLife Ion-Balance C should first be used to adjust the magnesium concentration, with the help of a test kit.

AquaLife Ion-Balance C provides 55000 ppm of magnesium. To avoid undesirable ionic imbalances, the product is formulated using magnesium chloride and magnesium sulfate, while maintaining the ratio of chloride and sulfate found in natural seawater. (NSW = 7.1:1). Like the other components of the AquaLife Simple Science Reef System, Ion-Balance C is produced using high-purity ingredients.
All components of the AquaLife Simple Science Reef System are free from contaminants such as ammonia, silicate, phosphate and organic matter.

Preserving the correct balance of important chemical components of seawater is crucial to
the long term success of every marine reef aquarium. Of primary importance to the survival of
corals, mollusks and many other reef invertebrates is the supply of calcium and carbonate
ions. Without these components in the correct ionic ratio, invertebrates cannot deposit
calcium carbonate in their skeletons or shells. Because organisms extract calcium and
carbonate ions from the surrounding water, regular supplementation is necessary to replenish
these ions.

Every reef aquarium is different in terms of the kind and number of organisms living in it, and
therefore the rate at which calcium and carbonate ions are removed from the water. It is
therefore impossible to give all-inclusive instructions for using this or any other liquid
supplement product. It is necessary to determine by means of water tests, the calcium
concentration, alkalinity and magnesium concentration of the aquarium. Once this information
is obtained, it is relatively easy to calculate the quantity of supplement to be added. Typical
ocean surface values for these parameters are: Magnesium1280 ppm; Calcium 420 ppm;
Alkalinity 2.5 meq/L (7 dKH)

Adjustment of the magnesium concentration should be done first. Unless magnesium is
present in sufficient quantity, the addition of calcium and alkalinity supplements will simply
result in chemical precipitation of calcium carbonate.

Formulated from high-purity ingredients, AquaLife Simple Science Calcium Part B contains
no silicate, nitrate, phosphate or organic matter, and was designed by a professional biologist
to be ionically balanced with AquaLife Simple Science Alkalinity Part C. Different brands of
calcium and alkalinity supplements should not be combined, to avoid imbalances. AquaLife
Simple Science Calcium Part B contains 74000 ppm of calcium.

Each ml of product added per gallon will increase the calcium concentration by 19.4 ppm
when used as directed. Use 1ml/10gal every other day for one week. Test the calcium and
follow instructions below. Use with equal parts AquaLife Simple Science Alkalinity Part C.
Do not mix products together. Add measured amount of product gradually, in an area of high
water movement.

Calculate the correct dosage. Divide the result by 7 for each daily dose, or by 3.5 for dosing
every other day.

1. Measure the calcium concentration of the aquarium.
2. Decide how much you wish to increase the calcium concentration. For example, if the
aquarium tests 380 ppm and you want to reach a target concentration of 420 ppm, the
amount of the increase is 40 ppm.
3. Multiply the amount of increase by the number of net gallons in the system.
4. Multiply the result from step three by 0.0515. The result is the number of milliliters of
supplement needed to reach the desired concentration.

To convert milliliters to:
• teaspoons, divide by 5.
• tablespoons, divide by 15.
• fluid ounces, divide by 30.
• cups, divide by 240.
