Should you shock after heavy rain?

Jim is right. As long as your chlorine levels are in line where they should be based on your CYA levels, it isn't really necessary.

I've seen a couple really big storms drop enough tree parts in the pool that I had persistent CC and shocked the pool in response. My pool's pH usually drops after rain.

My pool's pH usually drops after rain.

My pH does, too. We have had a ton of rain here in the past week --- like 3-4 inches. I had to add some Borax the other day which I don't have to do too often since my pH is pretty stable. I have also had to drain my pool twice already this week and may have to do so again this afternoon. Enough already. I may have to build an ark soon.
