Refugium light period

G'day Reefers,

In regards of the period of refugium lighting, i read that some people have the light on opposite to the main tank???

In laymans term. can someone please explain to me? whats the pros and cons of this technique? and is it ok to line up with the lighting of main tank?

That technique is the best. When the main lights are off, the fuge should be on. The photosynthesis going on with the macro algae replaces the photosynthesis of the corals, stabilizing the pH at night.

 

thanks for that, but is there a back fire if i dont follow this technique though?

 

no, just bigger ph swings. Another benefit is that nocturnal creature like pods and mysis may be transported to the DT during you fish's feeding times for finicky feeders as well.

 

I personally like to keep fuge lights on 24/7 as I like to use them mainly as a nutrient exporter.

 

Sweet!! thanks for all the inputs fellas! much appreciated!

Yes, low pH/large pH swings. That can be damaging to corals, other inverts, and especially fish, making the oxygen levels low at night.
