Karen, I'm working that into the new set-up of my ponds which will now consists of four lined, wooden troughs and two stock tanks with wooden skirting. I had a 6' round metal stock tank but found a second hand 9' blue plastic one a few months ago. The troughs consists of a 4x10' which is under construction right now, a 3x5' log cabin style which is in planning, a 4x6' to replace the one that fell apart during the move, and the little 3x4' plant filter. I'm also going to build a 4x8' marginal tank to go with the 4x4' that my lotus are in. This is to try to get rid of all kiddie pools.
Happy ponding,
Scott
