I have just replaced a 10 year old sand filter used with my above the ground pool, with a cartridge filter.

I was wondering if anyone has an opinion on which type of filter works best?

The reason for the change in filter type was because I was having a real issue the last two seasons with keeping my water clear- I changed filter media, and it still seemed to me that the filter was not removing particulate matter from the water, so I figured changing the type of filter was worth a shot.

What I can tell you is that the pool chemistry was "perfect" according to the local pool store water testing computer.

I have just started up my pool for this season with the cartridge filter and I want to know if I should expect a dramatic difference??

Thanks-
