Hey, I'm completley new to all this so forgive my ignorance!
I've got a 58L tank and wanted to add a few plants maybe 4 or 5, however i only have inert gravel substrate. I was wondering could I feed the plants with just a feed that is added to the water like Seachem Flourish or would I need to buy a special plant substrate? Also is a C02 system essential? I Dont want a heavily planted tank just a few real plants instead of plastic. Thanks for your help
