I got a great deal (free) on a slightly used pentair variable speed pump (1.5). I am looking at buying a sand filter and I want to buy the right size. Pool size is 24 round x 52 above ground. Been reading on here a lot and it seems that bigger is better, and I want to get it right the first time. Any suggestions would be appreciated. And on a happy note, we have finally started on the ground work for the pool, hope to get it out of the garage soon. Thanks in advance and I hope that everyone is having a wonderful day!
