How many watts for dawn/dusk in a 120 gal? - Aquarium Advice

runway1 · 07-18-2005, 02:10 PM

If you were using [acronym:ac27ca2ed5="Power compact fluorescent"]PC[/acronym:ac27ca2ed5] lights for dawn/dusk effects on a 120 [acronym:ac27ca2ed5="Gallon"]gal[/acronym:ac27ca2ed5] tank, how many watts would you use? I looking at a 2x28 watt setup. Is that too low?

There just for the dawn / dusk effect so low watts is fine. I have 2-28 watt 48" Reg T5 lights on my 125 for the same thing and they are great..
There the Current T5 lights.... Cheap and nice

*shrugs* I use the 2x65w (50/50) for my dusk/dawn. Typically 30min-1hr of on time before and after the [acronym:32254abfdc="Very high output fluorescent"]VHO[/acronym:32254abfdc]'s come on. [acronym:32254abfdc="Metal halide light"]MH[/acronym:32254abfdc] is for the middle four hours. I need to get a dimmer for my [acronym:32254abfdc="Very high output fluorescent"]VHO[/acronym:32254abfdc] ballast so it will slowly increase the brightness for the first and last 30 minutes of on time.... just haven't been able to find someone selling the dimmer for an Icecap660....

What is the best type of lighting setup for a 55gal tank. I really don't know anything about the diff lights. I'm still using my fresh water lighting. Should I change?

Andari, I would suggest starting a new thread for this. There's tons of information and options that are available. Lighting depends purely on what you plan on keeping in the tank.

schoeplein what color lights do you use for dawn/dusk? Your 130 watts isn't too bright?
