I am in the learning process on aerators. I have made my own. I have a little over an acre pond that runs to about 14' deep. I am currently using an AP100 septic pump with 3 100' 1/2" lines running off of it. The pump is working fine. I have had it going 24/7 for about a month. I have made my own diffusers but believe I need smaller and more bubbles. I am going to try soaker hose this weekend and if that doesn't work I will be buying air stones. If you need more "power" you can use a bigger line. I am looking at going to a 3/4" or 1" line. The 1/2" is working fine, but I think I can increase the longevity of the pump with a larger line i.e. reduced back pressure.
