Product Information

Swell's very own brand Swell Control Sludge is an efficient and cost effective way of keeping sludge at bay in your pond environment. Sludge is a build up of biological waste from fish, plants and other pond debris. It can result in very poor water conditions which affect the various life forms within.

This cost efficient system can treat up to 6,000 gallons/26,276 litres of pond water by simply placing the individual nuggets into the bio filter or pond water. The beneficial bacteria will then aid in the breakdown of the organic material that causes the sludge.

Easy to use, convenient nuggets make this one of the most versatile products around with no messy measuring or dosing needed. Part of our own branded range, it is of equal if not better quality than leading brands and always at an everyday low price.

Dosage:

Add one nugget per 1000 gallons / 4546 litres to your pond or filter. Continue at a rate of once a week during spring, summer and autumn.

Key Features:

  • Water soluble nuggets completely harmless to fish and pond livestock
  • Contains 6 easy to use nuggets
  • Easy to use, high value product
  • No measuring required
  • Beneficial bacteria from one nugget suitable for 1000 gallons / 4546 litres, during spring summer and autumn
  • This product is not a medication, but a beneficial bacteria which helps to break down organic material such as debris.

    I dont think they have had enough time to work completely but the water does seem to be clearing. They are rather large bombs and myponds are both small, and I lodged them into the pond, probably frightening the frogs as they landed with a very large plop. Time will tell whether the sludge comes to the surface so that I can net it away

    I look after 2 ponds and I bought these as an alternative to other makes of sludge buster and they have worked remarkably well. In previous years I have had to regularly clear out sludge from the filter in the pond pumps but this year I have hardly had to touch either pump. When I did have to clear out the pumps it was not sludge causing the pumps to run slow but other debris like leaves and seeds etc.
