The pool has been cold and crystal clear. Acid and Chlorine use is waaaaay down. The Calcium scaling looks to be dissolving a little - the white areas appear to be growing; maybe just higher contrast against the scale. Essentially, the pool has been very troublefree for over a month. And finally some rain. Not enough to make pumpout necessary, just makeup water, but at least it's not adding more CH!!
I vacuumed yesterday, but after the storm I have more debris and worms in the pool. Tomorrow I'm off work, so I think I'll vacuum again and scrub the walls some more. This year I'm going to get that CH down one way or another!
