I've been torn for the last year on this topic. At this point in technology I don't understand why they can't come up with a smartphone type of programming. X does X. I'd like to do my daily alk and Carbon dosings, as well as automatic water changes, but realistically I can see myself buying it and getting frustrated. I'd probably end up watching ph, which I can't change anyway, and using it as a safeguard for when my heater malfunctions. Then kick myself for spending $800 bucks on it.
