Thanks for the link, I was able to figure out the right amount of muratic acid to put in with that. Things are looking much better in the pool today, I can see the bottom, and it is only a little cloudy. There is also a bunch of floating stuff, which I'm thinking is dead baquasil. I noticed in previous thread that someone suggested putting a sock over the skimmer cup, and I did that, and it seems that is really helping catch the baquagoo.
