Best sand for high flow SPS dominated reef tank?

[Michigan Reefer]

I'm looking to add sand for a 75 gallon SPS dominated reef tank. I'll have two MP40's and an MP10 on high for flow and was only going to add maybe 1-2 20lb bags of sand to settle and have the rest barebottom. I don't really like the look of crushed coral, but looking for a thicker grain size of sand that won't blow around constantly and hopefully settle somewhere nicely in either a corner or around the rockwork. Carib sea special grade is 1.0-2.0mm grain size and next is Natural Reef or crushed coral at 3.0-5.5mm grain size which seems too big. I've only had Fiji pink and that usually blows around too much. Any suggestions or experience in this area? Thanks.

I use the Carib Sea Special Grade, and it works well.

I use Tropic Eden Reef Flakes in my 40 breeder with 2 MP40s.

Another vote for special grade.
It's big enough that flow doesn't toss it around, but small enough that fish and shrimp can move it.

Thanks for all the feedback, I'll see if my LFS has any special grade to look at.

Currently using Caribsea Live Sand in my RSR350. I am building a new tank, and going to use Special Grade because the sand is too fine and getting blown around.

Does the reef flakes move around at all with the high flow ??
