Can anyone provide some real world experience / reviews / opinions on running these? Did you notice a difference in general tank health afterwards?
For preventing disease (as opposed to just killing algae in the water column you will want a very good unit). I have a separate UV
unit running (don't like ones inside canisters as the canister flow rate is usually too high).
It has improved water clarity and may have restricted disease outbreaks to a single fish or school. That's just a suspicion from diseases that I thought would go more through the tank. However still had fungal, bacterial and ich infections with it running part-time. Size might be too small although it was the largest I could buy (options here limited, next time more research!).
Normally I would say water changes, etc will be just as good. I do plan to run it non-stop in about 4 months time when we go from winter to summer. The first heat wave of summer when tank temp jumps is when I seem to have troubles. That will be an interesting test of it.
At the moment it hides some filter pipes so I plan to continue with it. Will decide after using last replacement bulb.
