Tetra Pond AlgoFin is an effective and safe treatment for persistent blanketweed and other pond algae.

AlgoFin is an intensive treatment for the most frequently occurring algae types, such as blanketweed, floating algae and smear algae.

Tetra AlgoFin specifically targets algae and impedes its ability to photosynthesise. The treatment is effective over a period of around 2 - 3 weeks and can be reapplied to keep algae growth under control long-term.

Tetra Pond AlgoFin is available in 3 sizes:

  • Tetra Pond AlgoFin 250ml treats ponds up to 5,000 litres
  • Tetra Pond AlgoFin 500ml treats ponds up to 10,000 litres
  • Tetra Pond AlgoFin 1000ml treats ponds up to 20,000 litres

Add 50ml of AlgoFin for every 1,000 litres (220 gallons) of pond water.

AlgoFin can be re-treated at half the normal dose rate every 4 - 6 weeks, for the long term reduction of blanketweed growth.
