Eddie,
From the build, it looks like an old Oceanic tank. I had the 125-gallon version with the exact same middle brace and ran it fine for 3 years with 250-watt metal halides and the plusrite bulbs (SE 20k).
Here is what my tank looked like at it peak before I began my upgrade to the 210-gallon tank. I think you should be fine. Just keep the glass clean on top from salt creep and dust and on the bottom, clean it as well. If the water touches it at all, I would try to aim to cut your overflow teeth deeper to lower the tank water so that algae doesn't grow on it.
Excuse the overly blue picture but it was taken with my wife's Iphone that tends to blue up images really well.
You can see some of my biggest colonies were below that middle brace.
