Dyofix Lake Shadow was created specifically for use in a lake that formed part of a Grade 1 listed landscape.

The award-winning head gardener was concerned that having a blue lake would look unnatural and would not be convinced that the use of DyoFix Pond Blue would not leave his lake looking artificial.

We created a special blend of the three primary colours, red, yellow and blue so that anyone looking at the water would not know that any colour had been used at all.

Dyofix Lake Shadow creates an artificial shadow within the water to halt light from reaching the bottom, which in turn will inhibit or halt any growth of the dreaded algae.

Dyofix Lake Shadow uses the same tried and tested technology as the other Dyofix products, and are non-toxic European Food approved items, manufactured from organic sources.

Just 1 Kg will treat 4 million litres

Dyofix Lake Shadow is supplied in 1 Kg boxes containing cold water soluble sachets.

The individual sachets ensure even distribution in larger lakes and the potential of treating smaller ponds with minimum mess. One kilogram box will treat up to 4 million litres of lake water.

Application methods:

By supplying powders in water soluble sachets it is easy to calculate the number required to dose a lake or pond. In large lakes, if a boat is being used, simply drop sachets in different areas where they will dissolve releasing the Lake Shadow. By spreading the area, the time taken for the Lake Shadow to fully mix with the water is reduced.

Using sachets where a boat is not available. Facing the water with a breeze coming from behind, drop a few sachets along the edge and throw the others into the water. The breeze will move the water and Lake Shadow will dissolve and mix in quite freely. Lake Shadow will fully mix with all of the water using this method but may take a little longer.

Reference Samples

If reference samples are desired, it is suggested that these should be taken at least a week after the initial application. Samples should be in clear containers with a secure lid, labelled with the date and location and stored in a dark place. An initial comparison to tap water will show the amount of colour present in the water.
