I am on my 3rd season with my Hayward Dreamlike 175 lb sand filter. The pool stores say sand has to be replaced every 3-5 years. I think they just wanna sell sand. They say that the particles on new silica sand are square, like tiny cubes. Apparently these corners are what catches a lot of the junk, and they wear off so the particles are more rounded and then they don't filter good. What's the consensus here? On another note, the specs on the side say that the effective filter area is 1.8 sq ft. Huh? I look at the size of the tank and can't understand how something nearly 5 feet in circumference and nearly 2.5 feet tall that is full of sand can have such a tiny filter area. What's up with that?
