If you have a float and a rope marking the diffuser, it should be an easy propositon to drag the diffuser to shallower water.


I don't think moving a diffuser is so easy, at least for me. I have a similar situtation, 12' deep, 4 head diffuser weighted with gravel and weighted line. I also have to use a boat and paddle to accomplish this and this time of year is generally very windy.

My previous pond was just as deep and I didn't aerate it at all, I had my first fish kill at the 20 year mark after a winter. I think the amount of muck buildup makes a difference, if you have 2' of muck after many years then you have less depth and water in the pond.

I'm not running my aerator this winter.
