We just opened our pool and have a Coverstar automatic pool cover. We are supposed to get large hail tomorrow and about 2-3 inches of rain. I'm not too worried about the rain as the cover does have a pump placed on it. However, I was not sure if we should leave the cover on with the possibility of large hail. Will this damage the cover? I know these covers are tough since they are made to where people can walk on them but wanted to get advice from those who have been through this before.
