Remove sand?

[WhatCouldGoWrong71]

I started this tank (Reefer 250) on 7/1 with wet gulf rock dark cured for 30 days. Since then I have decided to go 100% SPS and have loaded it with frags. It's had fish (5) for about 45 - 60 days now. I can't seem the get the flow exactly how I think it should be. I am using 2 Nero 5s on the back wall and 2 Reefwave 45s on the sides. The sand has settled in in the back 4/5ths of the tank with the front 1/5th bare bottom due to flow. So far the only thing I have that comes and goes is periodically a visit from diatoms. I know more is likely to come, but this is where I am at. I'd like to pull this apart and rip the sand out of the tank, but what damage would that do at this point? I removed the stock sump and put a 20L in as I added a Reefmat 500 and RS's crappy idea of fitting this left an already less than ideal sump even in far worse shape. Doing so I picked up so sump floor space. Could I relocate gravel to my roller/skimmer chamber to serve as the bio function and eliminate any worry of its removal at this stage? Thoughts?

If you want to get ride of the sand you can slowly siphon it out during water changes. Or another option would be to add coarser sand to the front to keep it from shifting.
