do I need co2?
I plan on setting up my 2 gallon fluval spec as a planted tank with aquasoil and CRS.
I recently came across a great deal at my LFS on a Tom Perchlight 13w for $9
However, I'm starting to wonder if this high light means co2 injection will become necessary to prevent algae? This will be my first planted tank so co2 is still a little daunting to me. Was hoping to get by with just excel dosing. Not sure on specific plants yet, but I'd like to plant it fairly heavily with a nice lush carpet.
So what do you think? Would excel, possibly some floaters, less hours with the light on, etc. do the trick? Or will co2 make my life that much easier?
Thanks in advance!
