Tetra® No More Algae® fizz tabs control algae growth in freshwater aquariums, including algal blooms that cause green water and algae that grow on acrylic and glass. For regular maintenance, use Tetra® No More Algae® tablets once a month or as algae growth starts to appear.

For best results, wipe your tank clean before treating. Use one tablet for each 10 gallons of aquarium water. Do not use in tanks with live plants, snails or other invertebrates. Remove carbon from filter during use. This product is not for use in soft and/or acid water with low alkalinity. Repeat treatment when algae growth begins to appear.
