Pool installed this summer. We closed it up and used the pool cover that is like a big round tarp with grommet holes. There is a wire that goes around the pool through the grommets and then cranks tight. Pool guy said not to use milk/bleach jugs through grommet holes as they will rip open from weight. Well, with the Sharkline pool, the top of the poles are big and bulky and the wire does not fit snugly "under" them. We have had the cover come off the pool a few times now...it fills with rain water and then the wire "slips" above the pole top and the tarp sits on top of the pool water before we can pump the rainwater out. We did add a few milk jugs to some grommets but didn't pull it super tight to avoid ripping grommets. Anyone know what to do about this issue?
