Hey all, I've been reading this thread and following its advice for almost 5 years now. I am a chemistry teacher who loves the amount of real science that has gone into this site. Keep up the good work!
We do have some amazing science minded folks who contribute to this site. Also construction folks who share their knowledge, electricians, plasterers, etc. who are all generous with their time. The TroubleFreePool method *works* as you have seen.
