Tetra Algae Control™ liquid is highly effective against green water (algae blooms) as well as algae types that grow on the glass and decor. And it’s safe for planted aquariums. A precision dropper top helps you administer the proper dose to your aquarium.

Tetra’s state—of—the—art formula makes it the most highly concentrated algae control product available on the aquatic market today.

Directions for use:

To be used only in established aquariums (> 3 months old). Before applying, it is recommended you first remove as much algae as possible by cleaning the glass and decor. Be prepared to clean out additional algae as it is killed to prevent deterioration of water quality.

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.
