UV Sterilizer, FW use 4/29/12
I'm looking for your opinion regarding the usefulness of a UV Sterilizer on a 240 gallon freshwater Discus aquarium for the purpose of parasite, algae and disease control. And if you support the use of one, what size (watt) and gph would be required?
about the running costs (regular cleaning, new UV tube each year) then by all means add a UV steriliser, and some problems, like diatom blooms in the water column, should reduce or vanish. But as a general addition to a freshwater aquarium, you'd be better spending the money in other ways.
