I have my apex coming Friday as well. Should be fun. I plan on doing the same as you and putting the plugs on the back of the tank. have you thought about a shelf in the stand? I can't quite figure out where to place mine, but it seems a lot of the space up top is unused.
I have considered that, but I am worried it gets in the way of plumbing and stuff. I have my hands in the sump often enough that I'd rather not have to constantly move the shelf.
More updates and pics.
First, got two corals at LFS today. Not sure what they were, they were just on a "mix frag" rack. I'm pretty sure one is a monti and the other is a chalice. Or they might both be chalice.
I picked up the RBTA from a local reefer who was giving two of them away, I simply couldn't resist. I've had several of them before and love them. This nem would cost easily $150 or more, it's huge. And it's beautiful too!
He also gave me a free frag of multi headed hammer. Not 5 minutes into the tank and the GGRRRRR gorilla crab was eating the heads. So I moved the coral onto the top of a rock that I know for certain has two pistol shrimp inside of it. So now, if he wants dinner he's going to have to go through them. With any luck they'll kill him for me.

But you can see in the pic that's why the heads were so retracted he was eating them!
Lastly FTS
One last bit of bad news, I think the blenny might have ich. Which means I have to try to catch him and then also pull my clownfish out, QT them all and treat and then leave the DT fallow for a while. :mad2: I'll have to see if I can verify if that's what the blenny has.
