20 long question...

[rs1831]

I thinking about getting a 20 long to use as a frag tank down the road but for now I'm considering using it as a regular tank now until I move. I have a 70 but I would like a second tank. Would a 150 hqi reef optix be a good light for this tank? Anybody else have a good ideas for this size tank?
Thanks.

Lighting really depends on what you want to keep generalizations like MH is the ultimate reef lighting can be dangerous. Decide what type of corals you would like to keep first then work your light system around them. For example you wouldent want to keep polyps and mushrooms under MH for sure it could be done and they will adapt to the lighting eventually but it is really un-necesary to do so!
