Commercial pond dyes are non-toxic, high-quality, food colours providing a cost-effective method of controlling algae and weeds without affecting the health of fish, wildlife and plants.

Dyofix commercial pond and lake dyes are supplied in two forms; powder sachets to treat large bodies of water and a liquid solution for smaller fisheries and large ponds.


Non-toxic, eco-friendly Pond Blue dye for lakes will control algae and aquatic weeds that often cause serious problems, interfering with fishing, boating, swimming, and irrigation. The extremely dense growths of filamentous algae and submerged weeds that also cause serious problems to fish, as a result of night time oxygen depletion, will also be controlled.

  • Controls the growth of unsightly algae and weed

  • Hides fish from predators such as herons and cats

  • Gives a rich depth quality to water

  • Creates a beautiful contrast with plants & shrubs

  • Cost effective and easy to apply



Good bacteria, non-toxic, safe and easy to apply!

Those of you familiar with our DyoFix pond dyes will know that algae is not only unsightly but can be a serious problem. ByoFix is a biodegradable, non-toxic product that is both safe and beneficial to use in the aquatic environment.

Our ByoFix products introduce natural bacteria which break down the organic pollutants in ponds and lakes. They help maintain good dissolved oxygen levels; reduce toxicity and dispel foul odours; eliminate suspended organic matter; remove sludge and control disease.


The Rhodococcus and Rhodobacter bacteria in ByoFix 4X-PS is supplied in liquid form. It’s primarily used in ponds with high organic loads or sludge at the bottom. The probiotic species present consumes the organic matter for proliferation and growth thereby reducing the load.

Other advantages of ByoFix 4X-PS are:

  • Works in a wide range of salinity and turbidity

  • Effectively removes sludge within a few days

  • Highly concentrated Does not require fermenting before usage

  • Widely used in aquaculture and breeding ponds

ByoFix 4X-PS improves the water quality by controlling pH, reducing ammonia and nitrite levels within 2-3 days whilst eliminating suspended organic matter in the pond water. If there are bubbles in the water, they will disappear also. Once the waste organic matter or sludge depletes from the pond or lake the blue green algae cannot survive due to a lack of food.
