Hi All,

I know its been discussed before for corals, I believe 12 hours is
recommended, but what about FO. I'm waiting for tank to mature before I add
corals. I have one small Pec Clown. 80g tank 4 x 55W white (7.1K) and 1 x
42w actinic.

Its fairly dark during the day here in Scotland at this time of year so not
much natural light gets in. Should I just have the lights on in the evening
for my families benefit or is it better still to have on fort he 12 hours
the fish would get on a reef? I plan to switch on/off in sequence to emulate
it getting lighter and darker.

Thanks
Les
