Hi George seeing that you have some fissidens fontanus in your current set up , do you know if this will grow in a non co2 tank, or even with just liquid carbon? Thanks in advance . Cheers
Fissidens will grow in a non CO2 tank as I have been growing some for at least half a year now. Fissidens Fontanus is a slow growing plant and in my low tech tank it grows painfully slow but its not dying. Having CO2 will increase the growth rate as long as nutrient and light matches the CO2 going in. I'm not sure about liquid carbon as I don't use it.
