Hi,
My 75g tank is setup and I'm testing the water every 2 days, looking for the cycle to begin. I had some questions about lights and Refugium setup.

I have some CF lights on the system, just for the cycle, how long should the lights stay on? I have them running about 18 hr a day.

As for my Refugium I have about 5-6" of sand and some dry rock rubble I there now. I plan to add some plants or Cheato later. Should I have lights on the Refugium durning cycle too, if so what kind and how long?
