I had DIY CO2 in 2 litres of jell-o, piped into the 30... My dog bumped the stand hard enough to knock down the chamber... causing an enormous release of CO2, creating a foam of media and yeast, and pumping it through the airline. About 1/2 a cup apparently was injected through the airline, into the tank...

I evacuated all the inhabitants to other tanks, thankfully without much stress. Everything that was in the tank was bleached, and the tank itself was rinsed six or seven times.

Now to cycle the tank again... AGH. No more CO2 injection on my tanks at home, at least until I can find a place for the CO2 reactor which assures that this won't happen again...
 
I had the same thing happen to me, but dont be discouraged. I used metal hangers to create a "basket" if you will, to hold the 2liter bottle. The hook part of the hanger hooks/hangs on the back of the tank. Out of sight and out of the reach of any pesky cats/dogs to knock it over.
 
A big water change and some carbon filtering would have been enough....no need to bleach the tank, start over and recycle the tank again. :huh:
 
would the yeast harm the fish? I wanted to make sure if any yeast was left, it had absolutely minimal food sources with which to grow... Hoping that it wouldn't stay in the tank.

It may be overkill, but I just want to be 110% sure.

I took my other tank's filter medias, swished them around in the tank water, cranked the temp up to 90, and put in about 6ppm ammonia. Now it's time to pray to the nitrite gods, and wait wait wait wait wait.

I agree with Mr Slappy, no need to do all that, an emergency 60% water change and some carbon would have been fine, then do another 60% water the next day and anything that was in the tank should be diluted enough so as it would not affect the fish. If you don't feel safe with the DIY method, you could go the Co2 injection road, no worrys with yeast geeting in the tank.
 
1) possible pathogenesis
2) detriment to water quality
3) aesthetic determents/smell
 
If you leave the yeast in there it would be detrimental to your tank, but then again if you leave a dead fish in your tank that also would be detrimental. But yes yeast and sugar out of a fermenting DIY bottle in enough concentration will kill your fish, not instantly but it could be relatively quick , but again it would depend on the yeast to water ratio, in small concentrations it should be ok for a while(I dont recomend it though). A big water change would have been fine. :)
 
THAT'S BRILLIANT! It's like a vacuum trap from lab... I think I shall try that, and I've designed a holding device that will prevent it from being tipped or knocked over.

Even though I've done vacuum traps several times in protocols, I'd never thought about using the same premise on the CO2 injection system.
