My (new in June 2015) pool has been crystal clear all summer, but is now cloudy. I have ordered the TF-100 kit, but it's not here yet so I had my water tested at the pool store. Previous to finding this site, I would have my water tested there and add what they told me to. So far, have only had to add CYA once and muriatic acid several times.
I have a SWG so know that the CYA is a bit low here. Seems I also need to raise the TA. I want to shock the pool (which I've never done before).
In what order should I do these things? Should I shut off the SWG before shock?
PS>I've never backwashed the filter yet; it's 2 lbs. above its "new" pressure. Should I do that? If so, where in the order of the other things that need doing?
