Calcium is a major constituent of coralline algae, the skeletal material of hard corals and the skeletal needles of soft/leather corals. In many cases too low a calcium concentration retards coral and coralline algae growth.
Calcium also fulfills many important biological functions.
In a healthy aquarium, the growth and multiplication of corals, calcareous algae and other organisms can result in calcium depletion. To maintain a stable environment it is important that the calcium content should not fluctuate by more than 15 mg/L from the optimum range of 420 - 450 mg/L so regular testing should be carried out.
This means that any calcium test used should have an accuracy of significantly less than 15mg/L otherwise it will be difficult to monitor such fluctuations.
The Salifert test kit measures in steps of 5 mg/L and has an accuracy of 10 mg/L.
The color change is precise, detecting small but significant fluctuations in the concentration of calcium.
The test is not affected by magnesium.
Sufficient for 50-100 tests.
Can be used for marine water, freshwater and garden pond water
Ca-1 reagent contains sodium hydroxide and is strongly irritating to skin and eyes. In case of contact with skin wash with plenty of water. In case of contact with the eyes wash with plenty water and consult a physician immediately.
Not for consumption. Keep out of reach of children. If swallowed contact a physician immediately.
INSTRUCTIONS for usage.
Natural seawater contains 400 - 425 ppm calcium.
Seachem Reef Reactor Lg
Reef Reactor™ is a high-purity source of aragonite, which supplies all important elements for optimal ionic balance and robust coral growth and coloration in reef aquaria. It has a grain size of approximately 1-3 cm. (Reef Reactor™ Md is 0.5 - 1 cm). It is intended for use in calcium reactors where it is dissolved slowly with the addition of CO2. As it dissolves, it provides calcium, magnesium, strontium, potassium, and carbonates among other important elements for reef aquaria. It is excellent at increasing and stabilizing alkalinity, which also supports a stable pH and encourages the rapid formation of coral skeletal material. With high levels of both calcium and magnesium, it offers an excellent means of balanced supplementation for rapid growth and propagation of corals and calcareous animals in reef aquaria. It possesses the highest level of soluble potassium of all competing brands while exhibiting the lowest levels of both aluminum and phosphorus.
Rinse Reef Reactor™ prior to initial placement in your calcium reactor. The rate of water flow through the reactor in conjunction with the pH of the water inside the reactor will control the rate of media dissolution. Follow the manufacturer’s instructions furnished with the calcium reactor and adjust the rates of water flow and CO2 injection to attain the desired concentrations of calcium and alkalinity in the effluent.
Use Seachem’s Reef Status™: Magnesium and Reef Status™: Calcium test kits to measure alkalinity, calcium, and magnesium concentrations.
