Solid Loop-Loc. With or without center mesh

[waste]

Christopher, et al, I'll give you my take on the 2 covers. The solid ones, with the mesh 'drain, usually open clean with the exception of below the drain, which is a 4 x6' black patch, algae is usually at a bare minimum. The green mesh ones usually open with anywhere from a slight coating of algae to a fullblown bloom, complete with 'algae ropes' threading up through the water.
With that having been said, I'd still prefer the mesh cover. As Kirsten points out, the solid ones weigh as much as the elephant they're supposed to support . Taking care of the water with either cover is very easy, just use the tool they supply you with to uncover the corners and add a gal or 2 of bleach once a month when the water temp is above ~ 50 (I've also heard of folks adding bleach through the cover and then rinsing it - but I'm not sure I would do that) The difference between the water quality is easily overcome, but the extra work for the solid ones is (IMO) not worth it. Y'all have the advantage that my customers don't: you actually are willing to do a little work to maintain your pool .
Spudman, welcome to the forum! From your post here, I'll say that you will do very well on the forum!! - Again, a warm welcome - Waste

Opening early and closing late is the key to avoiding the green pool syndrome with the mesh covers. Downside to the mesh is you have to periodically lower the water level during the winter.
