All plants, surface or submerged, use the process of photosynthesis to thrive and grow, the whole process relies on red light to drive it. By blocking some or all of the red light by using the water column as a filter, the process of photosynthesis is interrupted with the result of little or no further growth.

Daylight, or white light is made up of a series of colours, collectively referred to as a spectrum. If a beam of white light is passed through a glass prisim, the white light splits onto seven visible colours with red shades at one end through to blues and violets at the other.

When a light source, such as a torch with a clear bulb is switched on, the observer would describe this as white light. If a blue filter is placed over the beam, the observer would see the the light as blue, it is important to realise that the other colours are being blocked by the filter, blue coloured water acts in the same way.

Water treated with DyoFix will only have a faint hint of colour.


Firstly, determine the approximate amount of water in your pond or lake (see below on how to calculate it).  This determines the product (and the amount required) most suited to your needs.

Then it is a choice of the colour shade.  The first thing to note is that the resulting colour of the water will be very pale after DyoFix has been applied, but a close inspection or comparison to tap water will reveal its presence.  Anyone wanting to disguise the fact that water has been treated will choose Shadow.

To calculate the volume of water in a pond, multiply the length, width and depth (using metres) by 1000 i.e. (L x W x D x 1000) the resulting figure is the total number of litres. Divide the result by the number of litres treated in the table below. If the volume of water is less than the number of litres treated, any unused product can be saved for futre use. To compensate for dilution by rainfall and light fading, we recommend, as a guide, a regular monthly top up of 10 to 15% of the initial dose.

Instructions for use

After calculating the amount required, introduce DyoFix Lake & Pond Colours into different parts of the lake or pond to help speed up the dispersion.
