The CO2 is more straightforward than I thought. I have a paintball set up. I have the paintball canister, an adapter I got off Amazon, a standard CO2 regulator, and a cheapy ceramic diffuser. I set it up to 1 bubble per second which keeps my drop checker green and it's all set. I turn it off at night to keep the levels from getting too high (and to save some money on CO2 refills).
The hard part is actually managing everything else. I've got high light and CO2, now I've got to get my water parameters in line. I've got a hair algae outbreak right now that's giving me fits.
I may have to turn up my CO2 a smidge and adjust my fertilization schedule.
Thanks for the compliments! Lucky really seems to enjoy all of the crypt spiralis growing in the back.
