Tetra Algae Control combats aquarium algae and works to keep it from returning. It provides broad spectrum control and is highly effective against green water (algae blooms) as well as algae types that grow on the glass and decor. Algae Control is plant-safe.
Directions: Add 1 drop per gallon of aquarium water. Dosage may be repeated if needed every three days for up to three total doses, then clean the aquarium of dead algae. For regular maintenance, use as algae starts to reappear.
Attention: Do not use in newly established aquariums less than three months old. Do not use in aquariums with invertebrates or crustaceans e.g. crabs, shrimps, or crayfish.
