Looks totally awesome. I'm eventually going to get to using a Omron PLC for my tank this summer. Looking at your circuit diagram it appears you are switching the 120V nuetral. I am curious as to why you chose not to switch the 120V hot side, as this would eliminate the electrical potential on your equipment when its not running.
