I have had my MP40 running for a couple of weeks and in that time I have played with all the settings. I really like the short pulse mode the best, I am getting a really nice wave moving across my tank and the corals seem to really like it. My only fear is that I can't help but think this mode is really hard on the pump, surging every few seconds. Has anyone been running in this mode for any length of time? I wouldn't want to prematurely wear out my motor because I am running in this mode all the time.
