    Lightbulb Advice for New Return Pump

    Just installed the FMK on my 92G corner tank and it is reading 228 GPH on the return pump. Tank is in good shape, but concerned about low turnover rate of tank at less than 3X per hour. Been up and running for 4 years.

    Looking for advice on if I should upgrade to a DC pump with turnover rate closer to 5-7X. If so, which pumps are the most compatible with Apex controller?

    Thanks to all that weigh in on this thread.

    The new COR pump from Neptune is around the corner.
    NSI members are already testing the pump so a couple more months and it should be out.

    Why not wait a little bit longer?

    Thanks for the input. It boils down to adequate vs. optimal. I think what I have now has been adequate. Now that I have feedback and data for the turns on my system...it is not optimal. After all, isn't optimal why we are in the Neptune Systems Community?!

    Think I am going to wait for the COR pump.

    I am in your same situation. 350 litre, 980 litre per hour.
    I was not aware of the low turnover until I got the flowmeter. I expected to have, at least, twice as much. This explain a few issues in my tank.

    I am also waiting for the COR15.
