Thank you, Janet! You took a huge load off my shoulders. I kept thinking "I really need to get that pool clean before I cover it". Now I'm just going to drain the water down, maybe throw some bleach in and circulate for good measure and cover it up. I'll probably try to open it early this year before the temps get too high and clean it up so that the water doesn't heat up too much. It's easier to clean with cool water, right? (less algae growth). Thanks again!
