Closing pool chems for BBB

Assuming pH & TA is good....
CYA is like 40
What should I get chlorine level too?
Also add polyquat style algecide or anything else?

Up to the SLAM level for your cya level. See: http://www.troublefreepool.com/pool-school/closing_in_ground_pool

Also add polyquat style algecide or anything else?

Some folks do, some don't add polyquat60. It is extra insurance. I don't, but my water freezes solid during the winter.

There were subsequent posts in this thread about the use of sequestrant at closing. Those posts turned into a hi-jack since OP never asked about them in the first place. Those posts have been moved to "Sequstrant or Not" in the "Agree to Disagree" forum.
