Anyone keep any kelp?

[MrPillow]

Anyone grow this, either in a sump/fuge or their main tank? Can't seem to find too many accounts on the web. Would a Marineland DB LED fixture be enough to keep kelp going in a tank that is 16" deep?

[Sniperhank]

You could probably keep it all under a 6500 bulb. I would watch it just because of its fast growth and that if under 24 hour lighting it will go sexual.

[MrPillow]

So it must be lit constantly?

[Sniperhank]

No, it must not be lit constantly. The 24 hour lighting will make it go sexual. I would keep it in a fuge with the opposite lighting as your display tank. I have my fuge lighting on from 7pm-3am.

Oh alright I misread. I am toying with the idea of putting some in my display, or some other form of macroalgae.
