What is the PH/KH of the tank. That will tell you what youre getting for Co2. As far as plant supplies, if your lazy like me, and have a piece of plastic in your wallet, buy online ferts for your plants. Otherwise, you could mix your own, which I may try(On a new tank that I'm setting up, no fish at all, no shrimp for a few weeks), but I'm always afraid that I'll screw up on the mix and kill off a tank :soda:
