just started this tank up a week ago. It has 26w of cfl lighting,flourite,and three glowlight tetras. Iam going to rig up the diy co2,I'd love a fast growing growing comapact ground cover with some taller plants in the back. I need suggestions and help. I really dont want to add any ferts. I do plan on adding about 10 galaxy rasboras or some chery barbs. Hopefully this will help with some nutirents for the plants.
