You're off to a good start, it seems, from what you've shown. I do have a suggestion, though. From what I can see in the pics, you have water movement coming from your sump return and two powerheads that appear to be MJ(1200s). Figuring that the amount of flow from your return is about (very roughly) 450gph and the two MJs give you a total of 600gph, together, then you've got just about 14X in gph, the water volume of your tank. I suggest that you increase that to at least 25X, better yet, to 30X. Coral health, rockwork cleanliness, etc. would benefit, IMO, if you do that. And, also important in the issue of water movement is the kind of movement that you have, which is essentially coming from traditional powerheads in your system. That's not the best type, being a narrow, strong direct kind of flow that they make. I think your reef would do better if you provided a broader, more random kind of flow which more closely simulates natural conditions. There are powerheads that do that, which range from the pricey to the less costly that are widely available now so that you could easily do that. There are even low cost “wavemakers†that you can get. The least I'd recommend is that you put hydor flow deflectors

on the two MJs. They are very inexpensive and I’ve found them to be reliable and effective, even in a 120-gallon tank. They would reduce the amount of flow coming from the MJs a little, so that’s something to consider in the overall question of how to improve your reef’s water movement.
