I'd say so. Flow and stability are the more important factors, as chalices are usually deeper water, lower light corals. My question is why keep compacts when you can buy a 2 bulb t5 fixture for so cheap nowadays? On both of my tanks, all I keep are pretty much chalices. Bought a 2 bulb fixture for both and an led to give it some pop and they are all doing great. Not sure how they compare and what the par levels are but if you can afford a hundred, maybe look into switching. Gl.
