I've had the RKE since it came out. Running 3 strips, SL1, NET and before my AI's came the MLC as well. I'm also running ReefKeeper2. I've been nothing but happy with it and it remains one of the best purchases I made.
I have the Reef Keeper Lite. I have a DC4, SL-1, ph and temp probes. I am still waiting for the Salinity probe that they have been working on. (seems like forever) It was somewhat hard to setup. But I am still working on it. Any one use the wavemaker programs it has?
