Which would be better, pressurized CO2 or more light?
I am in the 3rd week of fishless cycling my new 40 breeder. Things are going well, I am converting ammonia to nitrites. So far I have planted quite a bit of DHG, an amazon sword, a nana and a single water onion. I am currently running a single 36" Satellite LED+ which puts me on the lower end of low/medium. I am also running DIY CO2 and dosing EI. I have enough money right now to buy either some additional lighting or a used pressurized CO2 setup (10# tank with Azoo reg+solenoid). At this point, which would be the better investment?
