Coralline growth under LEDs?

[cgj]

I now have a 250W MH halide fixture and can say coralline growth is only good in the partially shaded areas... the direct light seems to kill alot of it.
Now, it also has some blue LEDs for nighttime. Does coralline grow well under those, or should I use my 65W blue actinic fixture for a few hours a day to supplement it?

how many LED's?

Add a 460/420nm 03 actinic to your hood, you should see some growth from this.

Theres 6 blue leds and 6 white. The fixture made by sunpod only includes the 12 leds and a single 250watt MH. I try to use my old 65w actinic for a few hours after the halides are off.
