It is a 10000KHey war,what is the kelvin of the MH?
If it is 10000K and it covers your whole tank,then the 2 blues will be just fine, but imo if you are running a 13000k i'll add 1 white t5.
OK, agreed, but my pincushions are only open 5 hours a day, you reckon that enough feeding time and photosynthesis ?Jaques talked about that corals only need 5hours of intinse light,he said that in the nature only 5hours of intense light will hit the corals.(it has something to do with the angel that the light hits the water, if it hit's at a 45 degree angel the light bounces off) something like that??
It makes sense if one thinks about it, because the most light is between 10:00-15:00. and your MH is your sharpest light that replecates the sun?
Hope this helps?
Check out your pincushions at night when the whole room is dark? Totally closedI think 5hours for photosynthesis is cool.
Some leathers feed at night, one of my leathers is only open at night and sometimes during day time, i don't know really why?

How far is your cushion from the MH?
Is yor MH coverng the entire tank?
Cool thanks for the advicewell if your cushion is open for the 5hours that MH is on, then i'll think that he will be o.k
If you have a really deep tank, i think you can get one more white globe but still keep the two blue ones
A year ago i had problems with algae and bacteria, i had my MH on for 3-4 hours for a couple of months and my corals still grew.
Not as well as under lower K value lamps, corals actually prefer 4000k lamps, it is us that prefer the white/blue look to the tank.OK, understand that, what I am trying work out is if all my lights can be blue.
At present I run 40% Blue and 60% White.
Can corals thrive under blue only ?
