Skimz Pur ARAG Media

Brand: Skimz
Product Code: Pur ARAG
Availability: In Stock

Skimz Pur ARAG is a complete calcium reactor media which composed of natural aragonite with a high concentration of calcium, carbonate, magnesium, strontium, potassium and other essential trace elements. This is the perfect media necessary for the growth of stony corals, such as SPS and LPS.

Pur ARAG has a grain size of 4-6mm to ensure good circulation and easy diffusion of carbon dioxide, which effectively reduces CO2 consumption.

Pur ARAG has high magnesium and strontium, that is used by the coral to actively control the growth of the different skeletal crystal components.

1. Follow the manufacturer’s instructions supplied with the calcium reactor.
2. Fill the reactor chamber with Pur ARAG media up to the height indicated by the manufacturer, in most cases this will be three quarters of the chamber or a bit higher.
3. Follow the manufacturer’s instructions to adjust the rates of water flow and CO2 injection and attain the desired concentrations of calcium and alkalinity in the effluent.
4. During the first couple of months you may need to measure alkalinity and calcium 2 to 4 times to ensure that parameters are within the desired ranges, and make adjustments to reactor system as required. Once the reactor set up has proven that it is maintaining the level, you can then stretch the time between tests.
