My whole fishroom is using UV sterilizers on the supply lines. Each reservoir has a sterilizer on the "output" side of each reservoir. I use the 14w,I think, because of the high water flow from each pump.
(2)300g, (2)210-220g, (1)180g, (1)125g and the (2)90g tanks each have UV sterilizers running on the output side of one of my Magnum canisters. I can't remember last losing a fish, having a disease, or fighting algae in those tanks. These are using either 7w or 9w sterilizers.
They can be costly. I was fortunate to get mine when a fish store went out of business. I paid a bulk price for tanks and equipment. These were in the lot. I do think that they pay for themselves in the long run.
