I'm still trying to decide on a lighting system for a 120gallon tank. I saw a kit that has 4 140 watt VHO
bulbs for what seems like a reasonable price.
So I have a few questions on this:
1. Is 520 watts or 4.6 watts per gallon considered 'moderate' lighting? I'm pretty sure it wouldn't be 'high'.
2. What is the difference between a 'canopy' and a 'retrofit' kit?
3. What sort of coral and inverts could I keep under this lighting? I'd like to eventually have some mushrooms, gorgonians, polyps, things of that sort and maybe some anenomes (the kind that clownfish like to hang out in). I haven't really researched any of this yet and it would be later on after the tank is up and running for a while till I even think about adding in these things.
4. How long do VHO
bulbs last on average before they would need to be replaced?
Thanks for your help!
