    So, I'm wrapping up a year of having my AquaController and full-time pH monitoring. Throughout the majority of the year, my pH would swing from around 8.05-8.25, hardly every falling below 8 or above 8.3 in nominal conditions.

    OK I know some of you thought it was sacrilege that I tore my 450-gallon system down. Numerous issues compiled and aided in the decision. First off was the system itself. I think anyone who builds their first dream system will tell you that a lot more thought went into building it than...
