I have read that you should move your diffuser in the winter to a more shallow location. I am getting ready to set up a 3 station dual head diffuser system here in Kentucky. I was going to run PVC from manifold to center of a 1.7 acre pond. then run 3 100 or so foot weighted hose sections to the dual head stations off of a 3 way. The pond has two fingers and a center round area that will be 16ft deep. My idea is that I want to run one station in each finger and one in the center. All ran from one trunk line and having a ball check at the stations hose mount to control the inbound air flow.

My question is how do you guys retrieve them from below safely without damage?

Do you tie a small bumper style float 1 to 2 ft under water to grasp and pull up? I don't want to disturb the rising bubbles with rope or chain.

Any ideas or suggestions about the system will be welcome as well.

God has blessed us with this day, what we do with it is up to us.
