Moved to filters forum.....Sorry if this is the wrong forum, but couldn't find anything real specific. I want to purchase a pool pre-filter that will connect to my garden hose for topping off the pool water during the summer. We are on well water, which is quite hard with a lot of iron (rust color). I googled the topic and found a product called Pleatco Pure Start, but the feedback was not convincingly positive. Any suggestions from members who have found a good solution?
