Why use AQUAFOREST Ca Plus in a reef aquarium?
The calcium is an essential element for the growth of stony corals, particularly SPS and LPS. Combined with the carbonates present in the water, it enables the formation of their calcareous skeleton. An insufficient concentration can considerably slow their development or even halt their growth when the deficiency becomes significant.
AQUAFOREST Ca Plus provides calcium in an easily assimilable form to compensate for losses and correct deficiencies. Its concentrated liquid formula allows precise adjustments, while its 1000 ml format is particularly suitable for reef aquariums requiring regular dosing to maintain a stable concentration.
What calcium level should be maintained in a marine aquarium?
AQUAFOREST recommends a calcium concentration between 380 and 460 mg/L (ppm). In practice, a level of around 400 to 450 mg/L is generally suitable for many reef aquariums. The goal is to maintain a stable value appropriate for the tank's salinity in order to promote regular calcification.
The effectiveness of supplementation also depends on the balance between calcium, magnesium and alkalinity. An appropriate KH is essential for proper coral calcification. AQUAFOREST particularly recommends using KH Plus or KH Buffer to maintain appropriate carbonate hardness. Regular tests or ICP analyses allow these parameters to be monitored and dosing to be adjusted.
AQUAFOREST Ca Plus 1000 ml dosage
The dosage depends on the actual water volume of the aquarium and the desired increase in calcium. Two Ca Plus formulations are available, with different concentrations:
- New formula (red badge): 10 ml increases calcium by 20 mg/L in 100 liters of water.
- Old formula (without red badge): 10 ml increases calcium by 15 mg/L in 100 liters of water.
Before each supplementation, it is recommended to measure the calcium level and calculate the required amount according to the aquarium's net volume. For the old formula, the maximum recommended dose is 20 ml per day for 100 liters of water. This limit should not be automatically applied to the new, more concentrated formulation. In the event of a significant deficiency, corrections should be made gradually in order to preserve parameter stability. The magnesium level should also be checked before adjusting calcium and alkalinity.
Usage advice and precautions
Ca Plus can be added gradually to a well-circulated area of the aquarium or to the sump to promote dispersion. A dosing pump can also be used to divide the doses and maintain a stable calcium level on a daily basis. It is preferable to space out calcium additions and solutions intended to increase KH in order to limit the risk of precipitation.
Warning: this product contains calcium chloride (CaCl2) and causes severe eye irritation. Wearing eye protection is recommended when handling it. If it gets into the eyes, rinse cautiously with water for several minutes, remove contact lenses if possible, and continue rinsing. If eye irritation persists, seek medical attention. Keep out of reach of children.
