I have a mesh safety cover contoured to my kidney shaped pool with a set of steps on each end. The PB installed it last year and informed me to get the water level to about 15" before it snows. I did so and got 4 small dime sized holes in the mesh last year. I think this was from some water puddling on top and re-freezing. Other than that seemed ok.
This year I installed the cover and water is about 24" below right now. The cover clearly stretched a bit this year and is already pretty saggy almost touching the water. It looks like a trampoline when windy! Thoughts? Keep it loose? Tighten the springs up? Add water to 15" again?
