Clarifier can have side affects that can cause more problems from what I have read, it can be a real useful tool also, but is usually saved for later rather than sooner. Not trying to kill your idea just want you to know why it is not often a first try thing. I think the emphasis of this site is education and know what the chemicals will do to your pool, before your put them in, or at least as much as possible so you do not go from bad to worse or in your case, fairly good to worse. Glad to see you are getting progress.
Did not take the Pool Store Guy's advice and buy it. I'm not committed to it, I am working to use time to clear it up.
I'm guessing that it will need it at the end, but we'll see, as long as the pool is getting clearer, we're good. With full floor visibility expected tomorrow, the pool will be safe to use, that's step one. I'm hoping to have a real testing kit in a few days and get the rest done. So far it's 100% chlorine/filtering, so we'll see how clear this gets.
