so if i get some co2 will i b fine or do i have 2 change the substrate also?phuunkee1;4808050; said:with standard lights, regular gravel and no CO2, those plants won't last too long.
If that's java fern on the far left, tie it or weight it down to that drift wood - its rhizome (root looking things) will attach to the wood. It will never 'take root' in gravel, whereas it doesn't have roots.
Java fern may actually be your best bet for 1st time plants - they like low light, can do without added CO2, don't have soil requirements and taste bad to fish, thus don't get eaten.
