I though I should put this in a new thread. I am having to replace my cartridge filter assembly after springing a leak. A friend of mine was over yesterday and told me that after changing from a cartridge to a DE filter, they experienced much clearer water. I'm sure this topic has probably been covered at length, with pros and cons, but I am not having much luck finding a search string that works. Can anyone offer their experience or links to some applicable threads?
