My initial concern was organics being contained in the filter and consuming chlorine versus getting them out of the pool and leaving the bleach to do it's job.

However, the past several days the birds seem to preferentially want to crap in my pool. I've been leaving the vac out ready to go, and am vacuuming daily, sometimes more. The crap is going into the filter (what the pump basket doesn't catch) and my FC has been holding fine, so I quit worrying about this
