I have a 27' AGP and will be closing it soon and need to buy a cover. I'm curious as to which to buy since I have seen solid (water pools on top) and mesh (filters debris, but lets water past). If you had to do it over again, which would you get and why? Also, Should I cover the water with the solar blanket or should I roll that up and store it with the pump & filter? Last, I have a 100 sq/ft media filter and was wondering after cleaning, should I store it in a water filled container or allow it to dry out as well? Thanks in advance!
