I gave up on Fish tanks, several years ago. I do good just to get my pool into shape once a year. I just opened it and it's OD Green and almost opaque, it's gunna take some work to get it in shape, I should'a opened it a few weeks back. <img src="/ubbthreads/images/graemlins/doh.gif" alt="" /> <img src="/ubbthreads/images/graemlins/sad.gif" alt="" />

Good luck. <img src="/ubbthreads/images/graemlins/crossfingers.gif" alt="" />
