Opened up to my normal green pool (can't seem to get around it with the new mesh cover). Only issue is this year my CYA was 0 for the first time ever. I know I shouldn't start shocking until I can raise it until at least 20 ppm. The problem is that I know I shouldn't backwash while adding stabilizer, yet the algae is bad so the filter is needing a lot of backwashing. The pressure raises quite a bit.
Any advice? So far a day hasn't seen an appreciable increase in CYA for me.
