Decided to bite the proverbial bullet and do a DIY CO2, I was going to try sticking the tube into the impeller of the filter. I'm scared. giggle. Never done CO2 before, I'm terrified that I'll end up killing fish.
I want to be careful cause my plan for this tank is to breed Galaxy Danio from an already captive bred source. I'm so taken by this fish that I want to help the captive bred population to hopefully reduce it from being snatched from the wild.
