Hi,
I have a sand filter and have replaced the sand this year. I have replaced the gauge, too. I put clarifier in yesterday and have white pieces of stuff in my pool right now. I just spent some time vacuuming to waste and scrubbed the walls again. The pool store where I buy my chemicals and get my water tested gave me the clarifier for free...LOL...early on I spent so much money in there I guess they feel they owe me. They want to see me with clear water, too!! I had a lot of dead teeny tiny particles in my pool. Lord knows they couldn't be alive with the volume of chlorine they've been sitting in. I have been working on this pool for a month. I wish I would have emptied the pool originally and started from fresh. It would have cost me less! However, I really would know as much as I do about pools now, I 'spose. I just don't know what to do next. The 4th of July is nearly here and our pool is cloudy, cloudy, cloudy. It's blue...but cloudy.
