Oase AlGo Universal - Total Algae Control 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. AlGo Universal 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 1,000 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. The treatment takes effect within approx. 2 to 3 weeks (assuming metabolic activity of 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.

Not been used yet, so I can't comment on its effectiveness

AquaActiv AlGo Universal 500ml

Too early to tell how effective this product is. However one immediate comment is that it is frothy and I would have preferred that it wasn't.
