Hi, newbie here.
Did a look thru and couldn't anything on this topic, but then again I could just be blind.
I'm curious as to what everyone suggest/thinks about how often you should change your sand in filter?
We have a hayward s2oo high rate sand filter. Last time hubby changed it, he said was roughly 5 years ago. The people at Leslie's are always trying to get me to buy new sand. No they have never done a water test for us, they just always look at his account and say we should change it.
I don't want to buy new sand if we dont need it. So I'm just looking for thoughts on this matter.
