    Some pointers for when you set it up. The exchange rate isn't always perfect. For some reason, there might be slight differences between the two heads. However, these pumps are consist in that exchange. Once you get the exchange rate figured out, you need to dial in the salinity of your saltwater storage container to compensate. If the pump takes out more water than it replaces, then the salinity of the container needs to be higher than your target salinity. If the pump puts in more than it takes out, then the salinity needs to be lower than your target. Greggs does the latter.

    Every 4-6 weeks, check the salinity of the display tank. I found that until I dialed in my resevouir salinity, I would drop or raise .001 salinity, which isn't a big deal. That could be due to skimmer discharge, dripping water out of the tank, creep, etc. Just periodically check the salinity of your tank.
    Hi Cody, thanks for the tips.
    I am headed off on vacation next week so I won't be setting this up until I get back. Just have to do a big WC before I leave.

    From my understanding, it should work from anywhere you can get internet access.

    even without internet it works. Once you program it then it just continues doing it everyday until one of the sensors tells it to stop.

    I have it setup on my tank and love it! As an additional safety Measure yo can put the apex flow meter on the in and out lines so that you can see both sides are working. I ave both auto-top and water change automated. I also so have a salinity probe to monitor that as well. Less things to worry about when I go on vacation.

    Because the exchange rate is not exact ya kinda need to dial it in. But once you do and can get a straight line then you're good to go!
