Swell Uk Control Sludge Pond Treatment Twin Pack

Swell Control Sludge is an efficient and cost-effective way of keeping sludge at bay in your garden pond. Sludge is a build-up of biological waste from fish, plants and other pond debris.

Simply place a nugget straight into your pond and/or filter. The beneficial bacteria packed into these nuggets will then help to breakdown the organic material in your pond. These nuggets are convenient and easy to use, with no measuring needed. They're economical too, and much cheaper than other alternatives.
