I have a 24' x 52" above ground Intex pool. I was using a pump that came from another pool that someone gave me. The filter is a swimpro sw36t, it uses 250 lbs of sand. The pump was a 1hp motor that died today. i need a replacement but I am broke. I found a 3/4 hp green machine pump for less than $100 on ebay. My question is will this be enough for the size of filter i am using?
