While I did say that UV and diatom filters could clear the water, neither are the preferred solution as they don't address the underlying issue. An appropriately-sized UV sterilizer will clear the water but you should get one only as a final polish (e.g., your water should be pretty clear to begin with) and to keep down disease...not as a substitute for water changes/feeding in moderation.
Diatom filters are not particularly practical as they will clog quickly in a large tank.
