I kind of highlighted the problem! How did your calcium and alkalinity get so high?
Do this:
#1 - Test your fill water -- is the calcium and alk that high in the fill?
#2 - If your fill water is from a well, does it have metal (iron, manganese) in it?
#3 - Are you using cal hypo 'shock'?
You'll need to lower your TA, but if your fill water is low in TA and calcium, it might be better to do a partial water replacement, so your calcium will also be lowered.
