Refgium lighting time

[Yas]

Hello,

I know the refugium light is supposed to be lit on when the display tank light turns off to prevent PH swing. What about keeping the refugium light on 24 hours a day? Will it still prevent PH swing? Is there any adverse effect?

Thank you for your input in advance!

You may end up driving the nutrients too low and cause the algae to die off, the phot period can be determined by your nutrient levels, if they are higher then you can leave it on longer but once they come down the photoperiod should be reduced.

Hi Tim,

That makes sense. I'll cut the light during day time as I currently have only one picasso crownfish.

Thank you for your input!
