I ended up going to the local pool place and getting one for $55.. an 18 foot cover.
Biggest issue i'm having right now is that water is collecting around the areas that are around the central tube i have in the middle.
Its weighing the whole thing down and actually caused the side up on the deck to pull into the pull, dragging the bricks that were on top of this area into the pool (no damage to liner i can see).. i had it attached with the chord to the two 2x4s that were screwed into the deck for the ladder, but somehow the weight pulled the line right up and over and yanked the bricks in.
I then took kite string and tried to tie off the two corners of my deck, securing it to the deck bottom.. but even with this, its pulled or slacked and is now causing 6-10" gaps and the cover down about 6" into the pool on the deck side, semi exposed.. (to the right in the images below, not seen, its pulled off a little less, but maybe 3-4")
Debating to just take a chance and leave it or try tying yet again.. the whole deck on one side makes this a pain.
I even put holes in the cover (i know dumb), but small ones, hoping the water would drain from the puddling areas, but it barely did, i guess because its too close to the surface.
There has to be an easier way to fix this.
