hey everyone sorry for the long time without an update have been very busy. well it looks like this ponds time is coming to a end. All the fish are getting massive and it just doesnt seam big enough anymore so right now im designing a 7k gal one to take its place. it will be 28'x8'x4'. It will use an overflow style sump with a 6'x3x4' Wet dry. Ill be puchasing several more evolution ES pumps to pump water from one end to the other to create more of a river like flow. if I get 3 more pumps thats 32,000gph after head loss. may buy 4 more and get 40,000gph we will see. Not going to be happening for a bit though. Was going to start this winter but I have to go to india so will most likely postpone commencement till early summer 2012. Just thought Id let you wall know im still alive!
