renovate my tank! overflow ideas

[asylumdown]

Well the house has been on the market for a year and a half at this point, and with oil prices plunging like the mercury in winter, I'm not confident it's going to sell any time soon, so we're talking about taking it off the market for a while. This of course means I don't have to worry about the tank looking pretty for showings and if I'm not going to be able to set up a new tank in a new house, I need a spring project!

I have always HATED my internal overflows and want them gone, so my plan (pending final spousal approval) is to put all the corals and fish I want to keep in my sump for a few weeks, drain the tank, and cut the buggers out.

I'm thinking I'll probably silicone two sheets of glass over the existing holes, but then I'll need to figure out what to replace them with.

What do you guys think? I want something relatively unobtrusive, and professional looking but I have limited space in the joist space on either side of the tank to run plumbing down (hence why the overflows were made to be internal).

Would you guys go with an internal cost to coast overflow with a bean animal set-up, or something more like this: http://reefbuilders.com/2014/11/10/h...g-accessories/ sadly, I would require three of those to handle the flow of my 2800-3000 kph return pump, so it's not ideal, and I'm not sure I'd have space for that many pipes.

I would Loooove a ghost overflow, but I don't have the space for the box that sits outside of the tank.

Any ideas? I'm thinking I'll need at least a 2" pipe to handle the flow.
