The AA serves to as a reducing agent to remove the iron stains from the surface. Once that is done it won't remove anymore. And then as you start to add Chlorine initially it will only react with the residual AA. So the whole reason for the Polyquat was to have an alternative algaecide in the water until your FC levels will hold again. I think you will be fine until Friday (two days).. They (the Poylquat people) recommend maintenance does weekly and you will have your sequestrant by then. I would just keep the pH as stable as possible.. We are not expecting any NorCal weather extremes in the next few days.. so let it ride!
