Wonder when its going to be tagged "Release Candidate 1." In reality, I've had no problems with the software for about 3 months now. In fact, I change my programming the same way as you do, Dennis. I'm anxiously awaiting the rumored ReefLink, but I think I'm going to have to go the Apex route instead. My tank is a year and a half now, and the sps I have, along with the 2 clams are now requiring daily attention to alk. This week I think I'm gong to pull the trigger on an Apex and go with 2 part dosing.
