Interesting, Ladia. So how often you think a 're-fluff' should occur? We did have our aerator in the vicinity but it has since moved so we will be putting two aerators out this summer. The initial one we had in a bucket of rocks but it probably tipped over or the current moved it as the bouy is close to the bank now. This winter was extremely harsh with winds and we've had some erosion along the edges of the pond and dock that I need to take care of this summer. I didn't want to put rip-rap (cosmetic) but I think I best do so.
