Karim,
Incredible build, I've read the whole thing and am impressed- it's the same level of detail I'll be doing when I can land somewhere for more than a year or two and get something established. LOVE the dedication to detail you've put into your tank! I have to ask, what kind of engineering background do you have? I have a background in CE (but a degree in Arch) and I feel like much of the over the top stuff you've done is the same thing I'd have done... Bravo!
As for the high velocity issue on your surges, my initial thought is running into a T with slotted pipe coming off both sides (capped or with their own blow off holes) and some amount of dissipation on the opposite side of the T with a smaller diameter blow off hole. This gives you some blow off in pressure from the initial part of the surge and then laminar flow out both sides of the T. You still get a little punch from the hole but most of the surge displacement flows out laminar. This will break up the direction of flow into potentially 3 (or 5) directions (one for the hole opposite the flow at the T and two laminars in varying directions, plus purge holes on the caps if you so choose). This will displace the surge and still give a cocaphany of 'wave crash' albeit at lower velocities in all directions, that would be pointable to lessen the stir of sand.
BRS did a little video on a laminar flow pump that was introduced at MACNA using some colored balls to show flow and I have to say I was impressed with the capability of a laminar flow powerhead. I'd purposely try and incorporate that kind of thing into a tank, and if by accident you need a solution that happens to be met by laminar, you're all the better for it in my opinion. Just tell everyone you meant to do it that way from the start
