    Can somebody explain how hour by hour programing works?

    Been searching for a few days for videos and threads and I can't find anything that explains how the programing works.

    In the screen shot, what exactly is my pump doing?
    I'm assuming at midnight, the pump starts in pulse mode and stays in pulse mode until 4 am and it swtiches to rincon? And then from 4am to 8am it stays in rincon and then switches to pulse, so on so forth? Am I getting it right? Since my last point on the there is at 12, what does my pump do betweetn 12 and 24?

    Your interpretation is correct.

    From 12:00 to 23:59, it will run Rincon/50%

    It appears that you are using the default Pulse period; using Pulse with that 0.25s period is not ideal. Sub-second pulse intervals are generally used for creating standing waves using Pipeline mode (not Pulse). You should probably bump that up to at least 1 second, or longer; experiment until you find a pulse period you like for your tank & inhabitants.

    It's also worthwhile to vary the flow throughout the day so all the fish and corals can get their ideal flow at different parts of the day. I like to do a lower average intensity at night (to make it easier for fish to sleep) and have the flow "cycle" every 6 hours personally. This is how I do mine with one WAV and one GYRE (the GYRE is about half as powerful as the WAV).





    You might be an engineer if...You have no life and can prove it mathematically.
