@TORX, I was talking about ReefAngel not ReefKeeper.
@Nonuser - For USD289 you get the basic setup: Controller, Relay Box (8 controllable outlets), pH probe, Temp probe, 2 float switches (ATO), cables, etc. I would recommend adding the wifi module (USD129) for control over the internet (from smartphones, tablets, computers). From here you can add anything you want based on your needs. Support is excellent on there forum. The system is based on Arduino, the source code is open source so you have the option of changing the code as you wish. The sky is the limit. You can easily replace the parts in case you have a problem. (only USD75 for controller board - happened to me after the controller took a bath:-()
I'm not sure how to put it... if you want full control, like to customize it, understand programming, are DIY and enjoy tinkering with your toys, then this is excellent and can make it way more powerful than any out of the box system. Otherwise I would go with Apex or ReefKeeper. It's like DIY LED Lights (if you know what you are doing

) or buying out of box LED Lights and be stuck with their limited configuration. Or, for example, you BBQ a steak the way you wanted it or go to a good restaurant and always get the same few good choices. I hope the summer is coming soon.

I'm not pushing ReefAngel and I agree that Apex is excellent. It was actually my first choice originally.
Anyway, any controller is better than none.
