I have heavy leaf traffic at my home and this is my first fall here, so I too have been debating some simlar kind of "semi-close" with a leaf cover.
I will likely need to buy one of those tools to raise the concrete anchors and get a leaf cover that fits those, but I was wondering, has anyone with a high volume of deciduous trees tried anything like what lee or I are thinking about doing?
Eg. I'm wondering if there'd be so much leaf litter getting through the net if it would actually be easier just to leaf rake daily. I want to keep the pool available for the odd October/Indian summer occasion.
The owners former to the foreclosed owners also told me that some years they actually just covered the pool but left it "open" by keeping the heat on in the pool house and the water circulating. I'm in Michigan. Apart from expensive, does this even sound viable? All equipment is indeed in the pool house and it IS possible to keep same from freezing. I believe they said it made for a much easier opening come spring.
Last thought, might benefit Lee as well -- has anyone ever retro-actively had an automatic cover installed, and might that (eventually) be a good solution for a pool surrounded by maples and oaks?

(Yes, you heard me, SURROUNDED by very very very TALL maple and oaks! -- It's a beautiful site...but not without its challenges...)
