Another option is to not cover the pool at all. I no longer cover mine and haven't for years because I hated the hassle of dealing with a cover. In the fall, I just scoop out leaves. By the time I close my pool, the leaves are already off the trees. I shock the pool and adjust the pH to around 7.8 or 7.9 to allow for some drop over the winter, lower the water level a little, disconnect pump, etc. and I'm done. I do get a little dirt in the pool over the winter, but that is easily vacuumed out in the spring. The water stays clear. I do open the pool pretty early because our temps get hot pretty quick and I want to be able to start chlorinating so algae doesn't get started. This works for me. I don't ever plan on using a winter cover on my pool again. Just wanted to throw this out there as an another option for you to think about.
