I have already 2 150W HQI's on my 90Gal. Planted tank. That puts me a little over 3 WPG. Low lighting to Mid. I am going to put in some PC 96W in the some unit that already has Act in there. I am going to replace them with eather dual 96W 10k or dual 96W 10K & 67K. Im wanting to go with the dual 96W 10K. What are your ideas?
