Oase AquaActiv AlGo Universal Total Algae Control 500ml

The ABC of algae control.

AlGo Universal works effectively against the most frequent algae species such as string algae as well as slime algae and suspended algae without causing any lasting damage to the pond ecosystem. The product specifically targets the algae organism and metabolism, causing the algae to die off gradually.

Remove as much algae as possible prior to use in order to avoid unnecessary oxygen deprivation. Ensure an adequate supply of oxygen. Shake bottle vigorously before use. Using the measuring cup, add 50ml to 1000 litres of pond water and distribute evenly. Additional dosage of half of the quantity is recommended after approx. 4 weeks in cases of strong algae growth. Takes effect within approx. 2 to 3 weeks (assuming metabolic activity on the algae). Remove dead algae manually. Switch off UVC equipment for 10 days during application. Pond plants may develop brown spots in rare cases, which disappear again quickly however.

500ml treats up to 10000L of water

  • Active against the most common algae species
  • Counteracts stubborn algae infestation
  • Effective and long-acting
  • Prevents further algae growth
  • Contributes significantly towards an algae-free pond
