Sorry - I forgot to list the CYA. It is high - about 100 - we've been using the 3" tabs from Costco all season (Aqua-chem brand).

We replaced the sand yesterday (it was 11 yr old). I used three 1.42 jugs of bleach (Great Value) to shock it last night...FC this morning was 10.5 and CC between .5 & 1.

I don't have a way to aerate....am I better off getting alk decreaser from pool store or using the posted method without aerating?
