After the water bags all leaked and the water boxes blew into the pool, I ran 8-foot wood stakes through the tarp loops and attached them to ground stakes with bungee cords. But the wind still got under the tarp. To avoid that upward pressure--and after getting a $4,600 bid for safety cover-- I'm considering these two options, and wondering if anyone has advice.
1. Weigh down the tarp edges with 2-inch lay-flat hose 3/4 filled with water. 200 feet of 6-bar hose is $150. I'm not sure if I need PVC elbows, but I can add those later.
2. Or, avoid the edge issue by getting a tarp that fits fully inside the pool, like a solar cover. Keep the edges from sinking using sealed PVC tubes and use bungee cords to hold the tubes close to the pool edge.

Advantages: This would be a single assembly, like other people have done with PVC or conduit. It would be easy to roll up and store. 2-inch ID hose filled with water would be at least as heavy as PVC or conduit filled with sand. If it's only 3/4 full, it should have a squat profile, increasing contact with the ground.
Disadvantages: I'd imagine that the freezing may eventually cause leaks, but those could be patched.
