Description
Tetra® Algae Control™ is formulated to remove unsightly algae fast from your aquarium. This liquid formula effectively combats aquarium algae and also works to prevent it from returning. This formula is highly effective against algal blooms that cause green water and works against algae that grow on glass and décor, such as blue-green algae (oscillatoria), diatoms, “brown algae” (synedra), hair algae (spirogyra) or blanketweed (oedogonium). Safely use Tetra Algae control in planted aquariums. The precision dropper helps you administer the proper dose to your aquarium. One drop treats one gallon of aquarium water. Before applying Tetra Algae Control, first remove as much algae as possible by cleaning the glass and décor. This allows the product to be most effective at reducing the remaining algae and inhibiting new algae growth. Remove activated carbon filters for 6 to 8 hours after dosing. Be prepared to clean out additional algae as it is killed to prevent deterioration of water quality. See product label for complete directions for use.
