Tim from Pool Discounters help us select a safety cover for our pool as we had so many issues last year trying to deal with a tarp and weights that would fall into the pool. We have a wood deck so we required special anchors for a wooden deck. The safety cover is hassle free, no more checking to see if the tarp is OK every day!
I would recommend Pool Discounters for all your pool needs, they are friendly, helpful and have good prices!
