T5 MH bulb advice

[dano_b]

I have a 3X 250 watt MH 4 X 39watt T5 six ft light fixture.
I'm looking for a bulb colour combo that best brings out the colour of coral and fish.

I was thinking about 20k XM mh and
Ati purple +
Ati ture actinic

Any ideas would be appreciated.
Thanks

I like the look I get when running 3 x 250 Watt 10K and 4-460nm blue HO T5 bulbs. That is a good combination in my opinion. Nice color and great coral growth. Just about unbeatable IMO.

I have also used 3 x 250 watt 14K and 4-460 and like that as well - a bit more color.

Both are good options.

If you like a slightly brighter tank a bit more growth, go with the 10K and 460nm T5 HO actinics.
