Sludge Remover


Treats 5,000 litres/

1,100 gallons

The build-up of sludge or mud on the pond bottom is created overtime from various waste materials including fish excrement, rotting vegetation, dead algae and fallen leaves to mention just a few.

Left unattended the sludge takes away vital oxygen from the life within the pond, creates excessive biological oxygen demand and encourages the build-up of nitrates and phosphates which encourage excessive algae growth. The situation is made worse by fish searching for food within the sludge and therefore constantly stirring up the debris giving the water a dirty haze and lack of clarity.

ClearWaters Sludge Remover contains natural heterotrophic bacteria's which when added to the pond instantly start to consume the sludge in a harmless way, which in turn reduces nitrate and phosphates and improves the overall health and cleanliness of the pond.

Use ClearWaters Sludge Remover after using algae treatment s such as Clearwaters Blanket Weed, in the spring and when sludge and detritus is noticeable on the pond bottom.

Always ensure adequate oxygen is present in the pond by continuous use of water and/or air pumps.

ClearWaters Sludge Remover is harmless to all pond fish species and pond wildlife.


Mix the correct amount in a watering can of pond water and disperse as evenly as possible over the pond surface.

Add 100ml of ClearWaters Sludge Remover per 1000 litres (220 gallons) of pond water.
