Your link didn't work for me.

Something to consider: I have 115 volt AC outdoor air pumps that are designed for septic tank aeration and work very well for me for my indoor systems. I used one sucessfully for shallow winter aeration two years ago until temps dropped into the single digits. Then the rubber diaphragms apparently got so stiff the pump stopped working, as when I brought the pump back inside and it warmed back up it was fine.

The pumps are sold as linear air pumps but in reality I think they are technically diaphragm pumps.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
