Blue Moon Light - On? Off? Time?
Okay. I've an older bulb running that covers pretty much most the tank. During the day it's not very noticable. But at night after the primary lights go out it's very nice.
Question: How long can I leave on? IE: Should I kill them at night or should they stay on 24x7?
I've been turning off about 1 hour AFTER the primary lights, but not sure if the fish are unhappy about that. (Surveys went out, but nobody responded)
Thanks in advance.
