NO WAY!!!!!!!!!!
Everything I just posted I accidentally deleted!!!!
K...Here goes again(LOL)
Congrats on the tank!! I think you will be happy with the decision you made
Any equipment advice: 'fuge size, set-up, plumbing, pump-size, skimmer, heaters, lighting...would be greatly welcomed
Where a fuge is concerned, I'd go with the biggest size you can get away with. One of your other tanks (the 55gal especially) would make a great sump! You can just buy glass and silicone in the baffles/chambers and turn that tank into a sump. That way, you can make each chamber the size you want it to be able to house whatever equipment you are using and make the refugium as big as you want/need it. Here are 2 links to give you some ideas on what you can do. The first link shows some tanks turned into sumps and the second shows some sump ideas (made out of acrylic) but can be replicated in the form of a glass tank.
http://www.wetdryfilter.com/WetDry Filters and Sumps.htm - This one shows a few glass tanks made sumps.
http://www.melevsreef.com/allmysumps.html - You cn look on the left column under the title "varied sumps" to see some examples.
Where the plumbing and pump size is concerned, you tank's overflows are good for 1200gph (600 per) so you will need a pump that will provide you with flow in that area or how much you'd want flowing through your sump. Just keep in mind you lose flow at different levels of height "head-loss" so remember to take that into consideration. For eg a mag12 gives you 1200 gph at 0ft, but at 4 ft you may only get about 1000 gph. I persoanlly like about 800 or so gph running through my sumps. For me, I feel it gives the skimmer time to pick up in-coming water, but some people prefer a lot more flow for various reasons so that's something you will have to decide on. As for the plumbing size, your overflows comes with a 1 inch drains and a 3/4 returns so you'll just have to buy the plumbing parts to accomodate them. If the return pump you are using has a 1 inch output, then you'll just have to buy a reducer to tie it in...No biggie
Here's a link to your overflow setup if you don't have a sheet on it already

As far as lighting, where you are mostly going with softies, you won't necessarily need metal halides. You could possible get away with just VHO's, T-5's or PCs. Not sure how you plan on mouting the lights, but there is an option for whatever you decide. If you want a fixture to hang from the roof, they make the kits, if you want a fixture to stand up on the tank, they havethem and if you want something you can screw up in a canopy, they have the retro kits as well for all the different forms of lighting so it is all up to how you want to go about it.
Well, that is just a few basic answers. If you give us some idea on which direction you want to go, we can all make suggestions and steer you in the right way
Good Luck!
