So is the Aqua Controller II just an outdated version of the current Aqua Controller III? I haven't seen the II online for sale but I could have missed it. The Jr. seems to do everything I'm looking for.

i am a little leary of having it control my calcium reactor - x10 issues make me nervous
The CO2 will be connected to one of the Direct Connections....so not even using the x10. Hopefully there is no issues with the Direct Connections since they are not affected by AC line noise :unsure
