Dude, dude, dude!!! This is a ReefAngel...go to ReefAngel.com and you'll find the same unit for only 219.00...and the ReefAngel package gives you a ph probe for that price. The support you get from the Reefangel community is just great...I have one, and although it took me a day to get it up and running, I love this controller. I does everything I want and it has a point and click software program to make changes, it also tracks my temp and ph over time. The community just created an iphone app to make changes remotely. Check it out...it isn't for someone who wants to avoid all tinkering, but it really is minimal work once you figure out the original programming.
