Refugium Question

[intarsiabox]

I would love to but the overflow just barely fit my 1" durso and the tank was drilled with the return lines inside the overflows on the back wall. The only way I could fit the stand pipes in was under the return lines. If I had the tank designed myself I would have had the returns outside the overflow or made the overflows larger. We're looking at getting a larger house in a year or two and then I'll be setting up a 180g. This is my first tank with overflows so at least I learned what I like and would change next time.
