Thanks to you all for input. It's obvious I have some more research to do.

Thanks again.

I would politely disagree that the sand never needs to be changed in a sand filter. Over time the sand does lose its effectiveness. Fresh sand looked under a microscope has tons of sharp edges, over time these wear down and the sand loses its effectiveness.

I recently switched from a hayward sand filter to a hayward 36 sqft vertical grid DE filter (DE3620).

So far I am very impressed with the DE filter. If you are very picky about your pool water filtration then DE is for you. If you like simplicity then stick with the sand filter.

I never tried DE in the sand filter but that is a good idea.

I'm currently adding DE to my sand filter (Thanks Carl and Al!!!) with excellent results. I also run my Dolphin every week. Once cycle to clean the pool, then another cycle to "polish" the water. I must say that between last year and this year, it has made a HUGE difference in the water clarity when I have the light on at night.

By the way, my parents have run a sand filter for at least 10 years and have never replaced the sand. Pool still looks as good as ever.
