Hey thanks FishinRod, I really didn't think of that. My small bottom pond floods sometimes from the nearby creek. My brother caught a creek chub a few years back. Don't need those in my big pond. Right now I only have Shellcrackers and YP. I am trying to get some HSB shipped to me right now. Seems Illinois is cracking down on pond fish shipped in. First place couldn't ship here. I haven't had any predators stocked since stocking the others. Your warning has made me rethink my pvc design. Here is what I have now attached. Later I will cut those slots much bigger. Then slip a drain tile sock over entire thing. I ordered a 10 gauge 100ft extension cord with the pump. Last night I tested it through the 100 ft 10 gauge plus 50 ft of 12 gauge and it started up just fine. Seems to be well built for the price. I will keep all data posted (including pump performance) I get back on this project so maybe someone else wont have to struggle so hard. :-) Thanks!
