Too Much Flow?

[Hempknight]

hello I'm running a fluval 306 and a hydor 850 GPH circulation and wave pump and having issues with sand blowing around anything I can do to fix this issue

You can lower the powerhead a bit and point it up towards the surface. It actually moves more water that way too.
In a pinch you can use an anemone guard on the powerhead too.

I think that the best solution is to use larger particle size sand.

It's tough to keep the fine stuff in one place under typical reef conditions.
