I agree, from the pic and description, I would find ways to turn up the flow and agitate the water surface.
For me, its a red flag to see no rock in the tank. The rocks provide the main surface area for nitrifying bateria, this basically means the more rock you have the stronger your biofilter will be, and I see you have very little rock. The rocks also provide hiding space for all the little micro-organisms that make up a reef ecosystem.
