1st - Is there a newsgroup dedicated to just pools? construction, maintenance, etc.? 2nd - I'm looking for advice about turning my pool into a salt water pool? I specifically interested in brands of salt water chlorinators and the correct amount of salt in the water. Additionally, I'd like to here about owners of salt water pools who also have water falls regarding salt deposits on the rocks and the wear and tear of the salt on the fall's pumps.
