My New Nano Tank Journal - 20 Gallons Long Tank

[MCC]

Question guys.... for my refugium light... is it okie to leave it off during day time??? Since i taped up the refugium with back paper... it doesnt get any light from my main tank during the day time anymore... my living room is not the brightest as the tank is in an area with out much light..but the room is not pitch dark ...its still very visible during day time....

So if i leave my lights off during day time for the refugium...would i get the pH drop issue that people get at night time when its pitch dark???

Thanks.... right now i have my light on 24/7... but if there isn't a need for it..i don't want the light to be on 24/7
