I'm about to start curing about 30# of LR and was wondering if I need a light on the rock?

Um, Nah...
You can run a short daily light cycle if it will make you feel better but it's not necessary unless you have a hitchhiker or something in the tank that will survive the cycle and requires light. Chances are that the light will just promote algae growth during this period.

No, you do not. Many feel it is preferable to not have any light in order to discourage nuisance algae once nitrates begin to climb....
I'm sure others will chime in....:wave:

+1 just make sure you have the correct temp, say 75+ as it does req some heat to cure.

Dont worry about a light. Its not needed. Just thrown in a heater and small powerhead and you're good to go.

hi,

Lights not really needed, just maybe a short photoperiod with low intensity and a a bit biased towards actinic component. Low light condition promotes coralline algae grow and limits nuisance algae grow...just what you are looking for... ;-)

Hope this help
