Hi. I'm new to the forum and have only had a pond for a year. I didn't start small!! We bought a 200 year old house built from clay, the hole they dug the clay from is our pond. It's about 40ft x 20ft and I don't honestly think it's been cleaned in the past 200 years!! Unfortunately by the end of the summer it mostly dries out. This reveals the extensive amount of black decaying sludge. Last year we added some lake worthy heavy duty bacteria stuff and it certainly worked a bit but wanted a quicker result. This year I decided to get try and rid of the sludge, it's around 2 ft deep at the edges and at least 4 ft deep near the middle. The pond would be around 10ft deep from top of water to bottom of sludge when full. I cannot afford £3000+ to have company in to dredge it so started digging. I've cleared the 2ft deep sludge to solid ground but with such steep sides this has been done by lobbing a shovel as high as possible, there is no way to get a wheelbarrow up and down. I just cannot see how I can do the middle. On one edge the previous owner has obviously dumped a load of roof tiles in as the sludge was only a few inches deep and it's reasonably solid to walk on. Is it possible to do this across the whole of the pond?? Tip something in rather than take sludge out and what should that something be?? It is a healthy pond, lots of wildlife, water-lilies, beautiful clear water when full but something needs to be done to make it safe. I have dogs who rarely go in but can do when overexcited, very hot, etc. They have gotten stuck near the edge and needed help out, thankfully without injury so far. I need this pond to have a stable bottom for their sake and mine. A fence is not an option. Sorry for the long post but I need help!! Thanks. xx
