need help on buying a sand filter

[dwd]

Hello,
I need help with buying a sand filter for my pool. I have a 21x 41 oval above ground pool. should I buy 150lbs sand one or the 200lbs ? also which pump 1.5 or the 2 hp. what would be a good make for this size pool. I'm looking for a good filter system that will keep my pool crystal clear. any help would be greatly appreciated......Thank You!
