Well it's that time of year when most people close there pools. We do not down here in Southeast Texas. It really does not get "that" cold for an extended period of time but with all the news going on I have to ask. When should I worry about my stenner pump. I can run the pool pump to keep water moving but the stenner goes down to 1/4" tube that would just sit and then there is the bleach in the tank.

5% bleach won't freeze until roughly 20 degrees, stronger bleach stays liquid even colder. You shouldn't have any problems with the bleach freezing unless it gets really cold, and then you will have much more serious problems elsewhere.
