I'm not exactly sure what I'd wanna keep as it would be atleast a year from now...
Hmm. Well it is difficult to advise on lights without knowing what you plan on keeping. At least you have a year to think about it.
I can give you a general rule of thumb though:
Lets say you want to keep SPSs and clams. I would definitely go for a MH
setup. Depending on how long your tank is, you may need more than one bulb. This is because the radius of one MH
bulb only has a "footprint" of about 24" in diameter. So if your tank is over 24" in length, more than one bulb would be needed.
On the other hand, lets say you go with a softie, shroom, LPS
tank. You would probably be fine selecting VHO
lighting. The number of bulbs and wattages would, again, be determined on the dimensions of the tank.
I hope I was able to help you out some. At least you have a year to research your lighting problem and get ideas from others.
