Hi. I'm new to the whole "high tech" planted tank deal...and so for the first time I want to try setting up a nano tank with DIY c02. The tank is 2.5 gallons, with a 27 watt "daylight" flourescent desklamp and a red sea nano filter. I was wondering what kind of C02 setup would work, and what parameters i'd be looking for..? I want to grow riccia, flame moss and blyxa japonica... thanks for any input!
