Bill and Pottsy:
Thanks for your input. I may try the larger diameter quality garden hose for approx. 100', then reduce to the 3/8" airline with an external connector for the remaining 100'. I will keep the bends to a minumum and straight line out to the desired location in approx 6-7' of water depth with the airstone sitting on a weighted platform off the lake bottom a few inches. Bill I will watch the 7" airstone and may replace it with the 10-12" rubber membrane. I didn't get a "freeze control tank". What is this item and how does it work for us cold winter guys? My supplier is only a few miles away and he can get it for me I hope if this is highly recommended? Thanks
Rowly
