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?
