Well, I kind of think I'm leaning towards leafnet IF I can get one at a reasonably lower price than the micromesh - a lot of places they were almost the same darn price! Wish I could leave it open, but with all the crap that would fall in, I'm afraid I would have to get a wetsuit and go diving every spring in the icy waters of Plum Ridge Beach (What we call the pool) to dredge out sludge and gunk. No thanks - I have Koi ponds I have to dredge out in the spring and its not pretty and nice to smell, don't want to start doing the pool too (XXXX times larger!) YIKES.
