Boche, I'm getting ready for aeration installation at my pond. Don't really know which is best system, but I will say this: Make sure the company is solid and capable of doing maintenance.

The ones I'm getting require minor maintenance every three months, major maintenance every year. Otherwise all the expense is for naught. I'm pretty sure this is true for most aerators.

If the aeration company goes out of business, you may have trouble keeping their stuff working. So check carefully before you buy; cheaper may not be so cheap in the long run.

Good luck!
