This will be my first year for opening a pool. Have a 24 ft AG pool.

I'm in Iowa so swim season will probably start late May. But today temps were in the upper 70's. Is there some guideline as far as when a person needs to open in order to avoid algae?

Temp still drops at night. As long as its still dropping should things stay okay?
Like as long as it doesn't stay above 60 degrees 24 hrs a day?

I haven't peeked under the cover since closing it last fall.

I don't have decking around the pool yet so the only way I could vacuum last year was by being in the pool. I'm 5' 4" and pool has 52" walls. Sooooo, I'd hate to open early when the water is way too cold to get in it.

Thanks,
Lori
