    Any explanation?



    Is there any reason my return pump, an abyzz 200, would reduce flow by 100 lph in a few seconds. The tank is new and virtually empty so no critter could get in. Only guess could be some rogue caulerpa but would this cause the flow reduction? Anyone experience something like this before?

    Could be a large chunk of sand or piece of algae that is partially clogging the flow sensor making it misread as well. It's also possible another device whose wire runs perpindicular and close to the flow sensor is creating noise that is offsetting the flow sensor reading.
