API Marine Magnesium Supplement 16oz

1.12 lb
$18.99
API Marine Magnesium raises and restores magnesium levels to maintain a thriving reef aquarium. The magnesium concentration of a reef aquarium should be between 1250-1450 ppm mg/L. The magnesium level gradually drops in reef aquariums as it is utilized. So, it is important to test magnesium levels weekly and add magnesium accordingly.
