Bactokoï: a 100% organic multi-purpose pond treatment!

Ponds must be restarted in spring as no bacteria remain, leading to poor water quality, odours and an increase in nitrites. Bactokoï is a living bacteria concentrate, ideal for starting or restarting your pond in the spring. Used as a starter, it contributes to biological balance by eliminating nitrites, nitrates and ammonia. If your pond is overstocked, water quality tends to deteriorate quickly. We recommend using Bactokoï bacteria to activate your garden pond or lake’s natural biological filtration mechanisms and achieve a magnificent algae- and odour-free pond!

For maintenance purposes, Bactokoï is a powerful algae and sludge remover. It effectively tackles silt, sludge, leaves and other organic matter. It also eliminates filamentous, invasive, floating and greenwater algae. Unlike industrial products, Bactokoï is 100% organic and non-toxic to fish, turtles and invertebrates. Use Bactokoï every month for clean, crystal-clear water.

Bactokoï is also recommended for preventing disease in Koi Carp and all cold-water fish species: common goldfish, comet, shubunkin, lionhead, telescope, ryukin, ranchu, oranda, pearlscale (chinshurin), veiltail, panda cory and lionchu. Bactokoï keeps your ornamental fish healthy and prevents losses.


Bactokoï has a careful balance of anaerobic and aerobic bacteria for starting and maintaining your pond. 100% organic product.

Instructions for use and recommendations

Recommended dosage:

  • 1 litre treats up to 30,000 litres of water.
  • 5 litres treat up to 100,000 litres of water.

On receipt, pour half of the contents of the container into the filter and the remaining half directly into the pond. Switch off the UV sterilizer for 24 hours.

Repeat monthly between spring and autumn.

We also recommend the daphbio® daphnia and microfauna kit to provide your cold-water fish with a natural food source. This organic food source will prevent indigestion and constipation in your fish.


Bactokoï should be kept at room temperature.
