I recently bought your 20x40 inground "mesh" pool cover. We've had a lot of rain recently and there is 6 inches of water on top of the cover. Since it's mesh, I assumed the water would go through the cover and the cover would rise as the water is now deeper underneath it. Instead, it's almost acting like a "solid" cover. So my question is, shoud I pump the water off of the top of the cover. I have a submersible pump that's easy enough to pump the water off.
