After changing my light setup, I can definitely tell a difference in some plants. Instead of using the GE P&A, I used my 9325 K PC's and put in a "nutrigrow" T12 in my ODNO fixture. My Rotala wallichii is bright pink on the tips, and everything else is going well.
Nothing is growing much since CO2 is not here yet, but I'm sure that will change once I get all the stuff in the mail..
Tank in transition! 55 gallons, hard water.
