I just got a Jebao cross-flow style wavemaker for my standard 90 gallon. It's the SCP-120. What flow settings are recommended? Even at the lowest settings this thing really hums... especially on top. Right now I have mixed with GSP, Xenia, various mushrooms, Cephastrea, Pavona. The goal is to have more SPS at the higher levels of my tank and a few clams.
