All excited that I bought a RKL - Then came the programming part. Had it working fine and now all it will recognize is the temp. probe. I feel like a complete idiot. Went so far as to get a few things going, then decided to start over and hit the factory reset. Then I went to web site and upgraded firmware after downloading reef keeper 2.0. I feel like going back to basics that have suited me fine for last 2-3 years. All I wanted to do was have it turn on and off lights and use as a wavemaker for 2 koralias, then expand a little down the road. Why is this so difficult?
