I have an above ground pool with an automatic chlorine feeder. I had the water tested today and for some reason there was no chlorine in the water at all. So I filled the feeder up to the brim with chlorine tabs. The problem is that when I turned the water shut off valve back on the pvc valve broke in the open position so I can't run the pump until I get that fixed. My question is, is it ok that the chlorine is just sitting in the feeder without the pool running? Will this damage the feeder or plumbing in any way?
