I bought this a couple years ago but have never used it to control a tank. I have used the reef angel wizard to set it up, check function, etc, but it’s too techie for me. I fired it up today and everything is working fine. The three prong ac cord is missing (borrowed one from my dc skimmer pump to test). I can probably come up with one at work tomorrow though. Also, the usb programming cord is a little rough looking on the controller end, but it works fine. No probes except for temp. PM with questions. $150 shipped.
