No. I wanted to go down the route of erradication, so fallow tank (ich can't survive without a fish after so long...so they say), and one of the following to kill it with the fish in a QT: copper; chloroquine phosphate, hyposalinity, is supposed to be 100% effective at killing it. In which case, no need for UV.
Secondly, UV also kills a tonne of plankton, and I run a deep sand bed, to allow for as much plankton as possible, which feeds the corals, and reduced nutrients. I wanted to keep it as natural as possible.
Not working out, as I had hoped. Having a rethink at the moment, but really not sure what to do.
