I new to the fourm and fairly new to pools. (this will be my first full summer)
We have a 27ft round AG with a sand filter.
I have done a pile of reading on this site and thought it was time to join and thank all those that have helped me.
My pool was very green when I opened it but i seem to be now on the right track with clearish water (still filtering dead algee) and chemestry good and steady!
