Hello Everyone I am a new member but have been reading questions and answers for a couple weeks now. I just bought a property with a 1 acre pond max depth 12 feet accoring to previous owner. I am told the pond has been here 50 years and see alot of muck in the shallows and am starting to look for a an aerator to help clean it up and make the pond healthier. Anyway my question is should I be looking for a rocking piston or rotary vein system.

Thanks
Jim
