I currently have a 46g setup with Hygrophila, Sagittaria Chilens, Wisteria, Javamoss and some javafern.

I have a current usa double cf fixture capable of holding two 96w bulbs for a total of 192watt. My tank is 20inches deep.

I am also using the Hagen co2 system (I know too small) and my substrate is eco-complete.

My question is. Should I be using both bulbs (192watt total) for my current setup or would that be too much light considering my co2, plants, etc. I don't want algae problems or should I use just one bulb. I have a 6700k bulb and a dual daylight (6700k/10,000k)

Thanks for any advice.
