Ready to shock again. Water is looking great but still having FC take nose dive overnight.
pH is 7.5
CYA is 65
I have 2 more lbs of CYA and 8.5 gal of 6% bleach.

Can I put int he CYA immediately after I add the bleach, while at shock level? It should bring the CYA level up to about 75 or 76.

I will be gone for 9 days starting this weekend and my husband doesn't do any of this, so I'm trying to get it in order so all he has to do is check the FC and pH while I'm gone.

Thanks!!
