Like Ted, I, too, prefer mesh. I've had a mesh cover that has lasted now 8 seasons and will go at least a ninth.

As for anchors, I presume you have to hammer-drill into the concrete and put the retractable concrete type in. There's a type for wood decks as well that I use, plus a special edge type that seems to be unique to FantaSea and Kayak pools.

But Ted's advice will be far more valuable than mine.
