We just bought a house that has a 24' round pool with 48" walls. The pump and filter were bad and needed replaced. I am new to this so I found a pump and filter package online. It was a Hayward DE EC30 filter with a 40 GPM pump. I called the company and was told that, after their calculations, this would be sufficient for my pool. Now, I realize that I should have researched online a bit more before purchasing, but all the information I have found on this pump and filter indicates that it is too small! Any information on this would be a great help! Is this pump and filter too small for my pool? Thanks in advance for helping a newbie!
