Wavebox Users -- Creative Water Level Advice Needed

[ostrow]

I had a wavebox on the reef that I lost this summer. To use it (Oceanic tank), I had to dremel the teeth on the overflow box by about 3/4".

I had ask the mfr of my new tank to make the overflow teeth extra long. Now, having paid for that and assuming it was done, I heard back that their jig for some reason would not allow them to do that.

I will still talk to them on Monday but their overflow boxes are glass, covered by ABS. So dremeling on my own is not going to be an option.

The teeth on their overflows are 1" long. I have a 5' long tank. Any ideas for lowering the water level enough to enable full use of the wavebox? Makes no sense to me to use the box on anything less than maximum wave as with a 5' tank you get about a 1.25" wave at best.

I'd love to hear from people who managed to figure out the dilemma without cutting the teeth or otherwise modifying the overflow box.

Thanks!
