    Dig 220 question

    I installed a Auto Pilot Dig 220 with a SC 60 cell , two years ago. Really made my maintenance easier and chemical fluctuation with Ph and Alk less frequent. It's been great !! But I am getting calcium buildup on the plates. I just cleaned them 2 weeks ago and they look like this now [attachment=1:1ic8e4t3]ImageUploadedByTapatalk1372956950.351275.jpg[/attachment:1ic8e4t3]

    This is the other side : what's the blue stuff ??[attachment=0:1ic8e4t3]ImageUploadedByTapatalk1372956985.500206.jpg[/attachment:1ic8e4t3]

    TFT test kit numbers :

    FC 4
    Alk 80
    PH 7.4

    That doesn't look like calcium, and your numbers indicate that there is next to no chance of calcium scaling inside the SWG (unless the PH somehow got astronomically high).

    Unfortunately, I'm stumped (unless CH is much higher than indicated).

    I double and tripled checked the CH it's at 100 , the water sample is a little more to the purple side rather than red before adding the R0012 but def changes to blue at the 10 drop mark.

    That is an unusual build up that does not look like Calcium. Do you have a gas heater or do you regularly use copper based algaecides? Any other chemicals that you are using on a periodic basis?

    Hi Sean ,
    No heater in the pool. I did use some HTH algae guard 3x concentrate in the pool at the beginning of June, here are the ingredients :
