Royal calcium chloride dihydrate CaCl2*2H2O
400 – 450 ppm (desired concentration).
We produce a highly pure calcium chloride dihydrate. Our calcium chloride dihydrate is a perfect solution to increase calcium levels in the aquarium and promote the rapid growth of coralline algae and SPS corals. Due to its purity, it can also be used in the pharmaceutical industry or in the food industry. As with all other salts, we carry out constant quality control of the products in our own laboratory.
Note: Available calcium also depends heavily on the amount of magnesium in the system. In other words, when the amount of available magnesium is depleted by, for example, pink calcifying algae, the amount of available calcium decreases through the development of calcite.
Available in 1kg and 4kg buckets.
Instructions
Prepare a 5 liter canister.
Dissolve 2 kg of Royal Calcium Chloride Dihydrate powder in 4 liters of reverse osmosis water and fill the rest with reverse osmosis water. Larger or smaller canisters can also be used, you just need to extrapolate the amounts you add for each canister.
Depending on the volume of the tank, each solution is now monitored manually to determine the quantities actually required. Before adding a solution, you must determine the current water values.
For example:
50 ml of this solution in a 500 liter tank.
Value before dosage = 400 mg calcium. After 2-3 hours you repeat the test and find that the calcium value after the second test is 420 mg calcium. In this example, 50 ml of this solution increased the calcium value by 20 mg/liter for a 500 liter tank.
Now program the dosing pump to add 7 ml of the solution once a day, so that 50 ml of the solution is spread over a week.
This allows you to calculate the calcium loss due to coral growth and add the amount required to achieve the desired levels.
