Dyofix Pond Black halts the growth of algae

  • Pond Black is used in smaller ponds where the need to stop algae growth and weed growth is important, however Pond Black is mainly used for its aesthetic qualities.

Pond Black absorbs and blocks all daylight, allowing no light to penetrate below the surface, hence the black appearance.

 

Your pond plants that have leaves and flowers above the surface of the water are not affected at all by the use of Pond Black. Fish are also safe in this environment but

Pond Black darkens the surface of your pond markedly, making it impossible to see the fish.

Aplication method

Pond Black is supplied in cold water soluble sachets, each sachet capable of treating a minimum of 6000 litres of pond water.

If more than one sachets are required, simply drop them into different parts of the pond. The sachet will dissolve to release the dye. The water can be stirred to speed up the mixing process.

Pond Black has fully mixed in when you cannot see below the surface of the water. Don't add any more at this stage.

Aplication method for very small ponds

It is suggested that 200g should be mixed in a known quantity of water, for example, 6 litres - use a watering can for the mixture. Carefully pour out the mixture into 6 x 1 litre bottles. 1 litre of the mixture will treat a minimum of 1000 litres.

Use the amount that proves to be sufficient and close the remaining bottle(s) and identify them as "DyoFix Pond Black Liquid" and store them in a dark place for future use. If the bottles have been standing for a long period, shake them before use.

 

     

How it works, the science in a simple form

What is daylight?

  • 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.

A little about Photosynthesis

  • All green plants need sunlight for their reproduction, the energy from sunlight acts upon a green pigment (chlorophyll) which combines with water and carbon dioxide from the local environment to produce sugars and oxygen. Chlorophyll absorbs red light (centred about 650nm). Leaves look green as blue and yellow are main colours reflected by chlorophyll.
  • Photosynthesis is the manufacturing of sugars from carbon dioxide and water, in the presence of chlorophyll and light energy. Oxygen is then released as waste from the process.
  • The light source used for photosynthesis is natural daylight. It is this element of photosynthesis that can be manipulated to stunt the growth of algae and submerged weeds.
  • In a pond containing clear water, light easily passes through and any plants or nutrients present use this to grow. Plants get taller and grow towards the surface and single cell organisms (such as algae) start to float towards the surface. It is the floating, or suspended cells that can make the pond water take on the "pea green soup" look.
  • By preventing some of the light from reaching below the surface of a pond, photosynthesis is interrupted in deep-lying pond life such as algae. However, surface life such as lily pads or reeds, which photosynthesis either on or above the surface of the water, will not be affected. As it is not practical or desirable to have ponds built indoors or permanently covered, it has become necessary to develop another way of preventing the light from reaching the base of the pond.
