Patio added near pool, pH thru the roof....

If your pool is at shock level, your pH reading may not be reliable.

I actually let the FC drift to a normal level today (mostly to see if the pH changed). It was at shock level for several days. You can see its dead algae (not "clingy" if you brush it), but it just seems to be suspended in the water for a lot longer than normal. Filter is running well, pressure started rising after brushing so I know its catching something. Maybe it just needs more time. Just seemed a little odd that one "off" day could muck up the works this much.
