fuge light lighting up main tank...

[ajbaquatics]

...Will the light from my fuge that leaks into my main tank cause a problem if I keep it on 24/7? I blacked out as much as i can, but there still seems to be a good amount of light getting into the tank. What do you all do to keep your cpr/jalli combos from letting light into the main tank?

The benefit that you will get from the refugium will far outway any problems associated with some small light leak from it. I would block off as much light as you can, however. You can cover all sides of the refugium with something like the black plastic aquarium background material. Just be sure to peak in their every day and make sure all is well.
