hi i have a 75 g glass tank i wonder if my lighting is doing the job
i have 4 - 40watt 6500k and 1- 20000k 32 watt and 1- 32 watt blue it looks dull but bright is that good 4 my coral????
 
what type of lights do you have? it looks dull (probably yellow) because you have 4 daylight bulbs to only two actinics/bkues.
 
Your lights will grow some corals just fine, but not may.

Mushroom corals, some leathers, some zoanthids (high up), and possibly even xenia or anthelia. Soft corals only!


T12, T10, and T8 bulbs are just not going to put out enough PAR (photosynthetically active radiation) for corals to thrive under.


In your case, the 6500K bulbs will give you more PAR than some other bulbs may be, but you probably could use 3 of the actinic blues and 3 6500K's. Wouldn't look as deep blue as some folks tanks, but you should be able to grow a few coral.



If you live anywhere near Wake Forest/Raleigh, shoot me a PM and I'll give you a free green star polyp frag. You'll have to keep it high in the tank.


As a side note, you have plenty of light to grow a very nice "planted tank" with caulerpa and other macroalgae. You can do this along with the mushrooms and such, so long as the plants don't shade the corals. There are a lot of very cool looking caulerpa out there, especially Caulerpa prolifera.
