Does anyone have any experience using diatom filters? I am trying to get a sense if they are worth it for water polishing and to a lesser extent, disease prevention. Can anyone recommend a specific filter and give me some insight on how much of a pain they are to clean and how much they cost to maintain? Are they worth the trouble? Any specific models to recommend? Thanks in advance..
