I leave mine on all night so I can always have a peak at what's going on no matter when it is. Moon lights use hardly any power, my fish still disappear for the night with them on or off and corals behave the same either way as well. The corals that feed at night start doing so when photosynthesis stops and moon lights don't have enough power for corals to start photosynthesis. You may or may not get things to spawn with moon lights but the only reason I use them is just so I can see what goes on in my tank at night and it is very different than the day and just as interesting in its own right.

I can buy that...Ill give it a whirl...I do also like the effect they give

Like the RKE I use the lunar cycle option on my Apex. So no.

What is RKE?

all night & day

same here 24/7 baby...why not eh:)

It's just 1 less thing to do.:twised:

except when im sleeping.. they are always on, so off for like 6-7 hrs.

since i notice the fish are active a lot when i have them on. plus in real life the moon isnt out every day of the month. hence lunar cycle controllers, but i guess it aint nature in your tank..
