    It's normal for the pressure to drop when you flush - I'd expect it to drop more.

    You're seeing a good example of why its important to be able to measure the TDS of the tap water.

    Chances are the membrane is bad. With 55 psi, and even if you had 40 degree water you should still be making 53 gpd.

    It sounds like you're ready for a new membrane based on the the troubleshooting you've done.
    When switching membranes, a matching flow restrictor is all that is required, and we have them on sale right now.
    If you've got any additional questions please feel free to give us a call as well, since we'd love to hear from you. Happy Reefing!
