Pond Boss Forums AERATION Systems questions Weighted or unweighted hose that is the question ?

Body of water is perfect bowel shaped 130ft across and 35ft deep at center. I figure I have 1,466,000 gallons in my aquarium. I have purchased a used Gast 0523 rotary vaned pump that puts out 4cfm and 10psi of pressure. It is too hot to experiment out side so I keep coming up with hairbrained ideas to build my aerator system. I will be purchasing 3 or 4 Vertex AirStation 9" diffuser disks to do the job, (CWS Environmental Clean Water Service, Inc. has the best price since shipping is free). Finally to the point, I thought about makin 1 or 2 weighted stands at a depth of 15ft 3 ft off the bottom with weighted hose and fight possible turbidity problems. OR Use cheaper thick walled contractor garden hose 150 ft long and fight possible problem of hose floating on surface but I could hang aerator head from a (yet determined sized) float in dead center of my pond at 15ft and not worry about kicking up localized muck. I am in awe of the level of intelligence and experience in this forum. Thanks Chuck
