Light's Out!

How long can I safely leave my lights off to kill off Red Slime without harming my corals? So far it's been today.

See if you can figure out what's causing your red slime as well. It'll likely come back after you return to your normal photoperiod.

3-5 days if not longer. wont permanently fix the problem by shutting light off. could be too much nutrients and lack of good flow.
