Pulsing Xenias

[ahullsb]

I love that thing. I would love to get a controller eventually, but for 10 bucks that thing is great. My 55 is only 15 inches deep, and with it on the end of the tank, it is nice to have water blowing against the front and back of the tank, as well as really pushing water along the surface towards the overflow. When it is stuck, I notice surface film, so it's doing something.

Capn,

This is a picture of my tank, I am running 250watt halides... the xenias seem to thrive towards the bottom of my tank with low flow.. they are pulsing all day, as soon as the flow picks up they stop pulsing. Now there are moving up the acrylic towards the light.

beautiful tank--thanks for showing the pic. With the lighting you have it can't be reason for them going towards the surface.
I wonder what the reason for that is.

Here is my 55 before I started hacking away at the xenia, fragging it and selling it back to my LFS. Mine did poorly under pc's. Once I switched to mh's they took off! They seem to like high light, and are doing fine with high flow. (As you can see they are next to a powerhead.) And they have grown a ton even though I battle very low alkalinity. My kh was around 7-8 for awhile before I decided to raise it. I have no detectable nitrates either and they have always pulsed. So there are no "rules" so far for this coral. I too believe that there is a perfectly good explanation for why the pulse or don't pulse, we just haven't figured it out yet!

another beautiful tank--thanks for showing--how long has it been up.
