Lighting and Refugium during cycle

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?

The lights don't need to be on for the tank to cycle.. also you will need to add a light to the fuge once you put cheato or mangroves in..

 

For now, you want total darkness in both the fuge and the tank.

After your cycle is complete you can start going with a lighting cycle.

You should time your lighting on the fuge and DT to be opposing eachother with an hour or so overlap between them.

Light during the cycle will only add to the nuisance algae problem.
