    quick closing question

    Is it a big deal if the water is not below 60 when I close the pool? We're going to be gone for break and I want to close it before then. I have a full, non mesh cover.

    quick closing question

    The reason we say below 60 is algae has a hard time forming in water temp's below 60.

    If you can't wait, you can use some polyquat 60 algaecide. Bring it to shock level for your CYA level.

    going to bring to shock level. does the solid cover help with the algae growth prevention? Don't have polyquat.

    Yes it will help. The water won't be exposed to the sun and you'll hold FC levels a lot longer. Cold water also helps with FC loss.

    Re: quick closing question

    I don't use algaecide and I have closed a few degrees above 60 (as high as 64) when leaves were coming down and it was the lesser of two evils to get it closed first and take my chances with algae rather than the certainty of a ton of leaves. I also have a solid cover and I have always opened to a clear pool going back to 2005. But I prefer to wait until below 60F if I can just to be safe. I will probably have to close above 60F again this year, as it has been a warm fall. You might not be as lucky--no guarantee here.
