Tropic Marin Bio Calcium Supplement 18oz

Tropic Marin Bio Calcium Supplement 18oz

$52.13



Biologically ideal magnesium supplement for reef aquariums. Some corals and coralline algae use magnesium, in addition to calcium and strontium, in the formation of skeleton structure. The addition of BIO-MAGNESIUM to the marine aquarium restores the crucial magnesium/calcium ratio to its natural seawater concentrations, ensuring optimal skeletal growth. Royal Item Number: ATM29432
