I agree, I think the key to this hobby is to emulate nature as much as possible... normal lighting schedule, steady temps, salinity, PH, etc..
I've seen mixed reviews on having your fuge light on 24/7, right now I'm testing leaving it on 24/7 to see if my macro grows better. To my surprise the bugs in my fuge seem to have adjusted to the 24/7 light... I know in my my tank the pods/worms only come out when its dark.
Maybe you should test it out and let us know your findings
