acans under 400w mh?

[walkerbrody]

I have a 110 x-high (30") and have 2x400w 20k mh. I was concidering some acans. Do I have too much light? Where should I place them?

Are these Acan Lords? If so, I'd place them in the lower 3rd of your tank. Not too much flow. They can be acclimated to high light.
