Adding light...

[Reefkeeper28]

How would you add OR3 bars to a tank since they are not dimmable could they hurt corals adding to much light. I currently have a maxspect r420r and adding 2 OR3 - 90 blue.

Turn one on at a time and start the time they are on low and ramp up

Ok so I'll just start with one and ramp up hours then add second and do same over time. Thanks sounds good
