Filter size for my pool

Is a 100# sand filter big enough for my 18' round AG pool?

There is a chance I may be able to get a free 200# filter. This is another reason I have been holding off on the inevitable switch to chlorine. I would not want to switch out my sand now and then get this bigger filter and have to do it again. The 100# worked well on Baquacil until last summer.
