Sludge Removal
Sludge is a very common problem in ponds; however, sludge removal is not as commonly practiced. Caused by a build up of decaying organic waste it can quickly lead to more serious problems. This layer of sludge acts as a food source for green water and algae. Left untreated it can lead to poisonous gases being released into the water and having fatal consequences for fish.
Our sludge removal products are completely natural and safe for fish, wildlife, pets and plants. They work as they would in a natural, wild environment to break up sludge in your pond and completely digest it. This saves you the hassle of having to hoover the pond or manually scoop out buckets full of sludge.
