Hi I am the owner of a small pool in the Bahamas that needs new equipment-----pool 12000 gallons .... Pool company recommends oversizing pump and filter ( 011018 intella vs pump and c2002 stay-clear filter).... The reasoning for oversize is that we are on an out-island and the electric rates are very very high.... Seems to make sense to me --any downside to oversizing besides initial cost of equipment.
