Pond Dyes To Control Algae and Weeds in Ponds and Lakes

Pond dyes to control algae

It can be very time consuming to repeatedly clear submerged weeds and algae that choke ponds, lakes and fisheries.

Applying our non-toxic pond dyes to control algae works because the coloured dye filters sunlight to disrupt the process of photosynthesis. This results in submerged weeds and algae being unable to grow, putting an end to the unsightly nuisance.

A safe non-toxic solution to algae control

Dyofix lake and pond colours are specially formulates dyes. They are manufactured using the highest quality colours.
The pond dyes are safe to use for humans , animals, fish, amphibians and insects.

Pond Dye for Large Lakes and Fisheries

Pond Blue powder is the original pond dye for large lakes and fisheries and remains the most popular and economical of our pond dyes to control algae and weed growth. As with all Dyofix products, Pond Blue is completely safe for fish and other wildlife.

Lake Shadow has proved very popular with estate managers that want to treat their water with an algae prevention product without a tint of blue. Lake Shadow provides a twilight effect in the water instead of blue.

C Special is the latest addition to the Dyofix pond dye range. It was developed during trials to see if the invasive species Crassula Helmsii could be controlled using dyes.
