I have a quite small pond at 100' X 50' X 6' Deep and have a 1/20HP .75CFM pump that I want to use to aerate the pond and also keep an area free of ice this winter. I heard you want bigger bubbles if you want to keep the ice away, so would I be best off not even running the line through an airstone? Or maybe just drilling a few holes in a pipe and making my own?

In the summer I'll be more worried about aeration so I will need an airstone then, but for now if I will benefit more from no stone I'd prefer to save the money.

Thanks for any help. This site is great and if my bank account wasn't already overdrawn I'd heavily consider a subscription.
