I have a 120 gallon tank which is now officially doing very well thanks to you guys, thank you for that! I am looking into messing around with a 10 gallon tank for fun. Probably mainly a shrimp tank with 4-5 tetras in it just for some variety. But naturally I could not set up a tank without plants so I have some questions... This is a small tank only 20" wide. The only T-5 light I saw online was 18" wide but it was 40 watts. That puts me at 4 Watts per gallon. I was hoping to just substitute Excel or a DIY CO2 for the small tank. Would dosing with Excel be sufficient if I am slamming the tank with 4 Watts per gallon? If not, what kind of light would you recommend for such a small tank? Just looking for ideas to get started. Trying to start off inexpensive, I have dropped enough $$$ into the big tank. Thanks !!!
