About Seachem Reef Calcium

Dosing instructions
Add 1 capful (5 mL) per 80 L (20 US gallons) twice a week. Amount or frequency can be increased based on growth response. Do not exceed 3 capfuls (15 mL) per 80 L per day. Do not mix directly with carbonate supplements; dose on alternate days or at least 30 minutes apart. Excess calcium may increase loss of alkalinity.
