So I've determined that I need to SLAM (as discussed here).
CYA ~80 +/- 10
CH 225 [I wonder if this is why I have white streaks coming off a lot of the tiling/stone...??]
I added 6 jugs of Clorox (121oz 8.25) this morning - I think this should bring the FC up to ~28.
My plan [please jump in if I'm missing something]: Let the filter run all day, check the FC and CC tonight after sun down and then re-check in the morning to compare. [Does the filter need to run all night as well??]
If FC has dropped by more than 1, then add enough clorox tomorrow AM to get it back up to ~28. Repeat.
Advice highly appreciated.
