Tetra No More Algae Tablets, 8 Count

Tetra No More Algae Tablets are fizz tabs for freshwater aquariums. Tetra says they remove existing algae from the water and control new growth. Each pack has 8 tablets, and they are designed for both glass and acrylic tanks.

How you use them

Drop a tablet into the tank and let it dissolve. For regular maintenance Tetra suggests once a month, or as soon as algae growth starts to appear. Check the label for how many tablets your tank volume needs; pre-measured tabs are convenient, but only if you dose for the right number of gallons.

Why a fizz tab

The appeal is simplicity. There is nothing to measure, no syringe and no spilled liquid. That suits keepers with one tank who want a set routine, such as dropping a tablet in on the first water change of each month.

Before you dose

• Scrape algae off the glass and remove loose growth, so less dead material breaks down in the tank.
• Add aeration while it works, since decaying algae uses oxygen.
• If you keep live plants, shrimp or snails, read the label carefully first. Algae treatments can affect more than algae.

Address the cause

Algae always comes from an imbalance of light and nutrients. Tablets help knock it back, but it will return unless you also:

• Cut the light period to 8 hours or less
• Feed only what fish eat in a couple of minutes
• Keep up regular partial water changes
• Keep the tank out of direct sunlight

Other options

For a liquid treatment with a measured dose, see API AlgaeFix. For manual removal without chemicals, a magnetic cleaner such as the Mag-Float keeps the glass clear between water changes. Many keepers combine both: a scraper for weekly glass care and a treatment only when a bloom gets ahead of them.

Who it suits

Freshwater fish-only tanks where algae keeps creeping onto the glass and decor, and the keeper wants a simple monthly step.
