I have a pond that was built in 1973 and is about 28' deep with virtually no maintenance. It has muck built up about 5' deep. Vegetation would grow up to the surface and then die. I started pulling it out by the boat load. I used a 3" trash pump to suck the muck out and pumped it to an above ground pool then I would let it settle and drain the water to my bait fish pond and let the muck drain to a pit from the other end of the pool. I then took my jet ski and fastened a plumbing 90 degree fitting to the jet on the ski I can cruise around the pond and blast water and air down into the muck even in the deepest part of the pond. Although in water 12' or less it mixes the muck pretty well. On top of that it creates a nice bloom for about a week and a half without having to buy fertilizer.
