1. It is cycled!
2. There are dwarf Pea Puffers at my LFS, so I'm getting two.
and 3. added DIY CO2, because I wanted to try it. Got it aimed at the intake of my filter, and it's working beautifully. Going at 3 DPS right now, and the Zebra Danio that are temporarily in there are doing fine, so I'm not worried about it changing too much about my tank params.
SO VERY EXCITED ABOUT THE PUFFERS. So very excited. So many snails are going to meet their dooooms >:}
"Less bad" does not equal "good".
