I'll keep trucking then. Perhaps turn the CO2 down a notch, although I did only just put the drop checker in 30 mins before that photo.
The fish are behaving fine. Trying to eat anything that goes in, such as the drop checker in the photo. Not seen them at the surface since setting up. I did use the filter media from my old setup, which I think has boosted the setup time.
