Ok as of 10:00 am this morning it looks like we are stain free. Some light areas that seem to go away with some brushing, so a good bruising all around will be today's task. Water is clearing up, can now see the drain in the deep end, but it's not crystal clear (yet).

CL is about 1.5 -(I say "about" because the little test kit w/drops & you match the colors. It matches the 1-2 mark) But I've been able to hold that level most of the week.

pH is about 7.0 - I added another two quarts of muriatic acid after taking that reading.

Been laying off the polyquat because prior to all this we doused the pool with about three bottles of the hTh algaecide (thinking the stain might have been algae). The water still has an odor to it and it foams up a bit when splashed around.

So what's my next move? Do I start thinking about bringing my levels back up & chlorinating using calcium hypochlorite granular chlorine? Or should I hold these levels for a while longer?
