Coralline can live in almost no light. It grows better in my skimmer that is barely hit with a curly-q energy saver bulb than in the DT under LEDs. I vote no lights on during the cycle. It causes more harm than good. Cycling is when your tank's nutrients are at an all time high....that plus light equals nuisance algae. It's not true that you will get the algae no matter what. After the nutrients are purged from the system you have a much less chance of being plagued by algae.
