Last post was about the awesome price of chlorine here in Central Florida. I needed some because my pool went to heck while I was away on business and the weather warmed from high in the low 60's to high in the upper 80's during the week I was gone. I bought 10 gal of 10% from my local pool store for $14 out the door. 5 gal a few filter cleanings and a lot of brushing later and my pool was clean.
