Hi APC,

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.

None of the plants you mention are considered 'high light' plants. If it were me, I'd cut down your lighting to half of the 192, especially since you don't have pressurized co2. Take it slowly at first, and adjust as you learn/go.

Thanks Bert. One final question, actually two.
If I added in Rotala Indica to the mix would that change anything and should I be fertilizing with my current setup.
I do have eco-complete and as mentioning using Hagen co2.

R. indica should be fine with that. Yes to the ferts, and don't forget your water changes.
