In consultation with a fishery scientist (Peter Dennis BSc.(Hons.), M.Sc., M.I.F.M.)
On Monday 8th March I have decided to add a blue lake dye to the Fishery, to combat the weed and algae growth which has already started to blossom this season.
Once applied the dye will take a few days to spread throughout the water.
Dyes do not work by any chemical reaction, instead they modify the conditions in the water. They prevent certain aspect of light transmission thereby helping to stall photosynthesis.
The dye has absolutely no effect on the fish or the wildlife of the lake.
It works like this;
Daylight (or white light) is made up of a series of colours, collectively referred to as a spectrum.
This is known because when a beam of white light is passed through a glass prism; the white light splits into seven visible colours with red shades at one end through to blues and violets at the other.
Filters block colours
When a white light source has a coloured filter placed over the beam the observer will then see the light as a colour, i.e. a green filter shows as green – blue as blue, etc.
It is useful to realize that when white light hits the filter, the other colours are being blocked. The filter is allowing only certain colours of the spectrum through.
Dyofix blocks the red end of the spectrum
By adding DyoFix to water, a filter is being created to block colours from the red end of the spectrum getting through to the bottom of your pond or lake.
How does this help?
Photosynthesis needs red light
All plants, surface or submerged use the process of photosynthesis to thrive and grow and the whole process relies on red light to drive it.
By adding a filter to the pond or lake water you are blocking some, or all, of the red light and the process of photosynthesis is interrupted, with the result of little or no further growth.
