Calcium Additives for Reef Aquariums: Julian Sprung's Calcium Concentrate from Two Little Fishies

*	Advanced calcium supplement for marine aquariums
*	Makes it easy to rapidly adjust calcium levels in aquariums
*	Helps maintain optimum water quality for growth of aquarium inhabitants

Julian Sprung's Reef Formula Calcium Concentrate rapidly raises the calcium concentration when the alkalinity level is already high. Also simultaneously lowers the alkalinity level, bringing both closer to a natural seawater ratio. When the calcium and alkalinity levels are properly balanced, stop using Calcium Concentrate, and continue using a balanced ion supplement such as Kalkwasser or C-Balance, which maintain alkalinity in addition to calcium concentration. Phosphate-, nitrate- and silicate-free. For marine aquariums. Add 1 tsp per 10 gallons.

Dosage
Add 1 capful (5 ml = 1 tsp) per 10 gallons to raise the calcium level approximately 50 mg/L. The effect on calcium concentration by a dosage depends on the alkalinity level, because high alkalinity causes a precipitation of some of the calcium dosed. Use a calcium test kit and an alkalinity test kit to monitor these parameters and determine the quantity of Calcium Concentrate needed to achieve the desired calcium level. Natural seawater at a specific gravity of 1.025 has a calcium level of approximately 400 mg/L and an alkalinity of 8 dkH. To promote coral growth the calcium level should be maintained above 350 mg/L and the alkalinity should be maintained between 8 and 12 dkH.

Caution
Add to a strong current stream for rapid distribution in the water. Do not mix with other supplements in a dosing reservoir. Keep at room temperature. Shelf life is 5 years.

Ingredients
Reverse Osmosis Purified Water, Calcium Chloride.

Contains no Phosphates, Nitrates, or Silicates.

Calcium Reactors

In nature, seawater bathes coral reefs in many minerals and elements. Calcium reactors automate the process of replenishing calcium as well as other minerals and trace elements.

Calcium Supplements

One of the most important aspects of proper reef care is calcium supplementation. Calcium is vital for the health and growth of corals and plays a crucial role maintaining high pH needed in marine systems.

Pros & Cons of Calcium Reactors

As calcium supplementation has become more automated, one of the more sophisticated means of achieving the desired goal is the use of the calcium reactor.

Simplify Calcium Supplementation

In nature, a steady supply of calcium is available to reef inhabitants from a variety of sources. In the reef aquarium, calcium must be added with calcium sipplements. A calcium reactor is an excellent delivery system for these supplements.
