I have been making some changes in the AP system. I am raising the circulating pumps from the bottom of the tanks. I have the tanks tied together with a 2 inch line from the bottom, where the original drain valve is. I have installed a sump pump 12 inches below the surface of tank #2. I tied it into the top of all tanks to discharge above the surface level to help in oxygenating the w3ater in the hot weather. The Blue Gill that were in tank #2 are now in tank#1. That puts the loading rate at 50 fish, all of which are at the 1/2 to 1 pound size. I am trying to eliminate the need to clean the filters on the pumps. This is an every 3-4 hour event that I need to stop. When I am all finished I am hoping to turn tank #2 into a giant swirl filter that can be cleaned every couple of days.  I will try to get some pics so you can see what I am talking about.
