Hi all, we have a new saltwater pool with 2 umbrella sleeves in the tanning ledge. What kind of umbrellas can we safely put in there? Aluminum, PVC etc. I've not been able to find any where the pole is made out of PVC so I'm not sure what to do here or where to find something that will work. I know these sleeves are very popular so there must be a good answer lol Thanks.
