Thanks, I got it. I emailed mark this morning with the link to the site with the skimmer for 255 by the time he got there the price had gone back up, just bad luck i guess. I asked him about lighting, do you use DE or SE I read somewhere on here that DE were better becuse they used less power per watt, were brighter, and were easier to change the bulb because the uv glass keeps the salt deposits off the sockets. He suggested i go with SE if price was a concern, but im not sure if there is enough price difference to warrant the extra hassle/ energy cost (if what i read is true).
