I am setting up a 5.5 g tank with a penguin 100 HOB. I will be using a 14watt screw in compact fl. 6500K. I am going bare bottom (no gravel) I would like to grow a carpet of Ricca over a nice rock. I will probably have 2-4 endlers and maybe some cherry shrimps. In this situation at 3 watts per gallon do you think I will need co2 or anything else for that matter.
Thanks Tony
