  1. Extra ports for apex system Review by Jason
    Product Rating:

    I mainly purchased this to add another temp sensor to my system. Also, added another i/o port which you can use to add another breakout box. Finally, another pH port is nice, if you want to have another pH measurement from you tank or sump. Overall useful module and I have experienced no issues with it to date. (Posted on 1/27/2015)

  2. Don't forget the temp probe Review by Lesd

    Works great - I added one to my Apex system to monitor my Calcium Reactor pH. If you want to use the temperature function, don't forget to purchase a temperature probe. This unit doesn't come with one. (Posted on 4/24/2011)
