Lights are off all day except for pictures.Your Params are looking good. Rule of thumb, atleast for me, as a beginner I would wait a month until I add things to the tank including CUC. Also, most people would tell you theres no need for the light during the cycle since that would only create a larger bloom. How are the koralias working for you? I had them on my super old 20 gallon and seemed to be super loud.
The koralias are super quiet.
