Need wave maker for 6 gallon cube

[IndigoAlive]

I have a Fluval betta cube 6gallon tank that I’ve converted into a reef tank, but with the current filtration it doesn’t get hardly any flow, I bought a hygger hg222 that has up to 660gph but on the lowest setting with the widest wave attachment but it just blows my sand all over, is there a better wave maker with less flow I could buy to keep it from blowing my sand all over the place?

Sicce voyager nano has a 270 gph and 535 gph which are good for small tanks, they put out a wide gentle flow compared to the hyyger which is like a rocket propeller.

the sicce voyager 2000 streams are awesome and form fitting
