Thanks everyone for the help - I apologize for the delay in following up. We are currently living in a hotel while our builder gets our new house ready for occupancy, and the frag tank with the lights in question is temporarily at my parents' house until we get in (this week, fingers crossed). As I'm a 4th grade teacher, and we went back to work this week, things have been a bit hectic and I haven't had the chance to get over to my folks' house to screenshot the settings, or try any of the other suggestions. But I am heading over there later today to do a water change and will follow up afterwards. Thanks again for your help!
Pete
