Availability : 0 In-Stock


Reef Foundation A from Red Sea is a complex mix of blended calcium and strontium salts that can be used in order to raise calcium and strontium levels in your aquarium. Both of these elements constitute the foundation for coral skeletons along with magnesium and carbonate and are therefore invaluable to the health of your corals.

This liquid supplement contains mixed elements in the ratio required by corals in order to develop and it is part of the complete Reef Care Program from Red Sea. It is very concentrated and 1 ml will be able to raise calcium levels by 2 ppm for 25 gallons (100 liters). It is available in multiple sizes including 500ml bottle and 1kg powder packages.

The elements, which are essential to proper coral skeletal development, need to be found in balanced proportions. Therefore it is necessary before using Red Sea Reef Foundation A to know with precision what the calcium levels in your reef aquarium are. You can determine this using the Red Sea Calcium Pro Test Kit and afterwards you can use the chart included in order to establish the proper dose.
