Wave pump placement

[NinjaReef12]

Hello I’m getting my tank ready for some coral , but I don’t know where to place my wave maker , is there a way to make the sand not move too much ? Also how do I know if it’s too strong for my fish ?

If your blowing that sand, too much speed.
You can put it way down pointing up, maybe that helps.
Turn it down unless it’s one speed, then IDK, replace with controller version?

Maybe rock on the left to break the flow up…

Fish can take a ton of flow.
