I have been reading up on UV sterilizers lately, and have come to a conclusion. No one has the same opinion. Some people use them, others think they could be a waste of money. Some use them all the time, while others put them on and off every so often. This is all too confusing. I guess my question to this forum is, are they helpful for a marine aquarium? How often does it have to be on, and why do you need such a large one for a larger tank if you allow it to run longer than you would on a smaller tank? I would think you could get away with a smaller one if it had to be on all the time, but I do not know if it needs to be on all the time. Please help with all this confusion. I am starting up a new system after two years, and I never owned a sterilizer before. I know not to use it during the cycling process, but what about after? Thanks.
