It would be tough to tell just by looking at a static picture. Watch your coral as you begin to add, and adjust accordingly. The key is creating turbulent flow and making sure you have no dead spots. Often effective is placing both powerheads about 1/3 down the glass aimed directly at each other from opposite sides. This creates really chaotic flow as each flow from each powerhead smash into each other. Putting the one on the left so low could also move your sand around a bit over time, and also makes it so you don't have any low flow areas on the bottom of the tank, which is often desired in combination with lower light for soft corals like mushrooms and zoas.
