Is Light Needed

[JMorris271]

I am trying to get some pieces of LR to help cycle a new tank.Would a light source help run things along?
Thanks for your answers.

I personally do not run lights for a few weeks. Then I run them for a few hours gradually increasing the light schedule over time. And if I were to see any sort of algae bloom I would cut the lights altogether or back them down considerably.

light is not necessary for a tank with only rock cycling in it.

Light is not necessary for your cycle to complete. In fact, it may increase your the potential for a nuisance algae outbreak.
