With a pond depth of 10ft, you will most likely benefit more from a bottom based diffuser system rather than a floating fountains. Fountains just dont provide that much aeration past the first few feet. You could combine the two to get the best of both worlds, but that would obviously be expensive. If you are new to aeration, I dont know if I would recommend building your own system without some solid input from a professional. There are variables to consider and the last thing you want is an undersized aeration system.

Here is a link to an article with some good general info on aeration systems Pond Aeration. I would also definitely try to get a copy of the Aeration issue from Pond Boss. It is a must read...probably the best information assembled on pond aeration.
