Reef Foundation C Supplement 500 ml
Red Sea Reef Colours C (Iron/Trace) is a balanced supplement to optimise the growth and robustness of coral skeletons.
This product contains a blend of magnesium salts, provided in the correct biological ratio to provide for the needs of coral growth. They are naturally depleted in a healthy aquarium, so it's vital to restore the levels for strong healthy coral formations.
1ml will raise the Mg level of 100 litres (25gal) by 1ppm
