Beach bum,
You must be the filter man

, yes it is an Emp 400. I use it for circulation and carbon. I run carbon 2 days per week because of the softies I have in the tank. You can't see them in this picture, but I have a nice little Sarcophyton cf elegans, a finger leather, and shrooms. I run the carbon to cut down on the chemical warfare a little. Also, when I create a "storm" I use it to
trap detritus. But mostly, it is for aereation. I keep the tubes that drive the wheels pointed into the water to break it up for agitation. I also
dose kalk 24/7 ito the filter.
Hey Fish,
The only thing the emperor has bothered is the Symphyllia? sp in the bottom left. It is one of those angel/brain things. I figured if he is eating on it he likes it. If the coral doesn't make it I will consider itan expensive meal

. He hasn't bothered any other coral including Fungia, elegance, shrooms or anything.
Thanks for the compliments folks. There are several on this board that have been around for a while that I have learned a lot from. My tank wouldn't be possible without places like this! So to those that have helped and, perhaps, not even known it, I say thank you

.
