Can I add co2 to my walstad tank? So I have a 29 gallon walstad style tank with 1 inch of topsoil and 2 inches of gravel mixxed with flourite. Question is could I add a nutrafin co2 system thing that I have lying around or would this create a giant algae mess. My lighting is 2 shoplight fixtures with 40 watt bulbs=160 watts, obviously it hangs over the sides of the tank so I don't get 5wpg. |
