API Marine AlgaeFix should be used weekly to control algae growth, as part of regular care to reduce aquarium maintenance.

API Marine AlgaeFix is an EPA registered product, and will not harm any live element of your saltwater or reef aquarium.

Instructions

Add 1/5 teaspoon for each 10 U.S. gallons or 1 teaspoon for each 50 U.S. gallons of aquarium water. Repeat dose every 3 days until algae is controlled.
