I need some recommendations. We just got our fish tank up and running with a few fish in it and it has cycled for approximately 40 days. I just got an email tonight stating that they were going to cut the power on the school during spring break. I do have a generator that I can put in place of it but that's going to get expensive. What are the must-have's to run? Pump, wavemakers, lights? Are there any other recommendations other than a generator? Do I need to run the generator 24 hours a day ? I don't know how long they're going to shut it off I'm going to say worst-case and Ariel which would be nine days .
