Yeah, I kind of wondered if that wattage wouldn't be a bit excessive. I was thinking one dual lamp might not be enough - 48 watts. I just watched my 20 gallon go through 2 months of green water algae because of the summer sun. Even though it was in a remote corner of the living room it still picked up enough residual light to tip it over the edge.
I looked long and hard at pressurized CO2. I suspect I'll be there at some point, maybe sooner rather than later. Struggling with the price. Christmas is coming in a few months?
I have a C2 on my 20 gallon and really like it as well - very quiet and easy to maintain.
Thanks for the thoughts.
