Dusk & Dawn controls

[MattGecko]

Just recived my CustomSeaLife PC15232-Retrofit (2=32watt) with dusk & dawn controls.  

Does anyone use dusk & dawn lighting? If so, for how long?

 

This light is awsome, I cant wait to get LR/LS in my Mini-Bow.

If you mean leaving the actinics on for a hour ealier and hour later, then, yes thats what I do.

 

It kind of prepares the tank for the full blast of the white lights.  Maybe helpful in some way.

i do this also. im pretty sure most people do it. this prevents your corals and livestock from being shocked from the sudden burst of lighting

I use a metal halide system with flourescent actinic so it gives a little big of dawn/dask effect. The MH bulb takes ~15 minutes to give out it's full strength.

Something else I've seen that looks interesting

Anybody got one ?

I also use the dawn/dusk effect with my actinics. I've run my tank without it before for about 5 months and found that my fish and corals don't seem to care if there's a dawn/dusk effect. I only do it now because I can (I wasn't using actinics before) and it looks kinda cool.

That memolux thing looks interesting. Too bad they dont have a 120 V version. I guess you can only use it in Europe and Asia.

There is probably something out here in the Americas that mimic that.

here is a little computer that will handle quite a bit for you.  things from light times, wave makers, CO2, Temp....

 

it is spendy though.
