Some Lighting Questions...

[LittleReef]

Well, I have 4 GLO 54w T5 HO's. 2 Actinics, and 2 k18,000 and 4 Individual reflectors. I'm going to get 1 250w MH. (Reflector as well)

My questions are:

1. How low can I put some SPS corals?
2. Do the reflectors affect the depth that I can keep SPS?
3. Are these too strong for some corals?
4. If I added a 250w MH, would I be able to see a major difference in the colors of my corals?
5. Saying I got the MH, and saying that I already had 2 actinics, what would be the optimal bulb for me if I wanted the neon to show, but not too blue?
6. With the MH, how low could I keep SPS corals?
7. Are there some corals I shouldn't keep with only 4 T5's?



Thanks for reading!

1) Depends on tank depth.
2) Yes.
3) The halide can be.
4) Depending on K value and water condition.
5) Depending on actinic wavelength and power output.
6) Again, depends on tank depth.
7) Yes.
