sterilizer will not change the need for routine water exchanges. I'd only recommend UV
sterilizers for large tanks and those that experience a lot of turnover in livestock, like LFS
. They are indiscriminate in the microbes they kill. Reef tanks rely heavily on microbes.
You're best bet is to test the water regularly, keep the nitrates down, have plenty of snails and hermits, a little rock blenny helps too...you can cut light time to 8 hours a day and if the tank is near a window, shade the part the sunlight glares on.
If you are going to college and won't be able to care for the tank, then I'd suggest you find someone to take them if you can't find someone to take care of them.
We, as a people, know so much more about outer space than we do about our own oceans. This lack of knowledge can very well spell the dangers that lay in wait for us.
The oceans surely would swallow us before a rock comes down to smite the planet of it's life.
