Hi all,
I've been using the BBB system for almost a year with fantastic results. Thanks for all the help and support in the forums. I've been going through the scale forums as I have a scale issue. My pool surround is some type of canyon stone, which has a ring of scale around the top. I've scrubbed and used acid directly (with goggles and gloves, of course - still not a smart thing to do). It goes away slightly but never completely. A bigger problem is the waterfall. It is some type of brown rock - some of it some kind of moss-growing rock - I'm not sure. Anyway, there is some nice scale at the water interface and this rock is pretty porous. So far, acid wash doesn't seem to have done much. I've posted my latest chemistry below. It sounds like I need to get the CH down, CYA down, and try to get the pH lower. Looks like some drainage is ahead for me. Does anyone have any suggestions on what could be done shorter term? Thanks.
FC - 4.0
CC - 0.5
pH - 7.5 (just put acid in - usually runs at 7.8)
TA - 90
CH - 330
CYA - 80
