My daughter did her morning fish count and all the neons are still alive, whew. Actually the gills are less red too, and the drop checker is down from lime green to just green. I think one bubble per second is the way to go. I'll keep an eye out for algae though, if it stunts plant growth too much.
Still, it got me to thinking about surface flow, and the fact that the CO2 bubbles can just sit under the HOB outflow forever without any interruption. So I bought a circulation pump to get some crosstank flow going, a Koralia 240 I plan to aim from the far corner towards the surface and towards the HOB. it might shoosh the red root floaters around a bit, but it will also increase oxygenation and prevent any protein skins on the surface - plus who knows, maybe some of the fish might like a bit of current to play in.
Oh, last night my son noticed that 3 out of the 5 Emperors have "colored up" - they have that pearlescent sheen to their skin, and one even has that cool blue sheen. I guess they're adults now - definitely bigger than when we first got them, plus their fins are getting those black highlights, and the tails are growing out to the "crown" formation. Fun!
