AC Jr. questions

[pickle311]

I currently have the Reefkeeper and I'm considering selling it and buying the AC Jr. The main reason I'm considering the switch is because I have Coralvue ballast and the freak out the RK. Does the ACJr. have any issues with these ballast? Also, I see that it can control PH, what do I need to buy to enable that function other than a PH probe?
Thanks

I'm not aware of any ballast issues with the Jr or the direct connect boxes. If you have a Coralvue ballast with either a DC8 or DC4 please chime in and confirm that it works.
