I am planning on getting more rock but im not sure how to aquascape it in a good way to have the best placement for coral bscause i mainly want a reef with a few fish. Especially with the flow and existing aquascape.What are you trying to accomplish with the tank? Sandbed looks thin and rocks look like they are in the low side as well. If you want a reef more than a FOWLR than I’d add more. After that you can gauge flow, lighting and water quality
