Pulse Coral Question
 

Is it normal for pulse corals not to pulse if there is sufficent flow in the tank?

Do you mean Xenia?

In my previous tank, it didn't pulse in high current. So, I put it where there was low current and it started pulsing. =)

Yes, xenias.

Depends on the Xenia species, I have 2 in my tank and only the silver bar pulses the other just sitts there.

I have noticed that lighting more than flow affects the pulsing. I went from PC to MH and the Xenia started pulsing a lot more and a lot faster. If they are getting pushed around by the flow they wont pulse as much.

I re-positioned them higher up right under the spray bar outflow. Still some current there but not as much as deeper down. They started to extend more and I did notice a pulse every so often.

i'm gonna have to say that flow has much more to do with xenias pulsing than lighting does. when i switched from 2x70's to a 400 they all pulsed the same, however when ever since i rearranged my rockwork and positioned the colony beside the koralia, it just sits there, hope that helps?
