DyoFix Pond Black is used in smaller ponds where the desire to halt algae and weed growth is important, but principally the product is used for aesthetic purposes. DyoFix Pond Black is designed to absorb/block daylight, allowing none to penetrate below the surface, hence the black appearance.

Plants with leaves and flowers above the surface of the water are not affected by the use of Dyofix small garden pond Black. Fish would also be safe in this environment, but the product will darken the surface of the pond making it impossible to see them.

DyoFix Pond Black Dosage Rates:

200g Dissolvable Sachet | Treats 6,000 Litres

DyoFix Pond Black Application:

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.

DyoFix Pond Black Application 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.
