Sorry,,, I was a DIY CO2... but I bet you didn't go to the link provided...
But in it you would find quote::
I am using DIY C02, with jello, fed into a filter.
I've used this many times before and this particular
bottle had been bubbling successfully for over a week,
with no problem. For a reason I can't understand, it
suddenly bubbled over into the tank sometime during
the night. Although there was red jello residue
throughout the whole air line, the tank had very
slight brownish residue, with no sign of red. Upon
waking I found my fish dead.
End Quote
But, even though, since I have had so much feed back
I will one day get a CO2 pump...
When my knownledge gets strong enough
I'll be able to use a CO2 pump wisely.

Please don't. Otherwise, when anything goes wrong, you will simply
blame the "CO2 pump".

In that case, it was most likely that the person, using a yeast system
to generate CO2, had the yeast mixture enter the tank. The yeast
mixture pollutes the water, the yeast growing consumes oxygen, etc.
This can happen in several cases:
1) The bottle gets knocked over. Usually by a small child or a pet.
2) When mixing up a yeast mixture, it's common to use very warm water
to properly activate the yeast. If you prepare the mix, and cap the
bottle and connect it right away, you might have problems. The
cooling mixture will contract, drawing water from the tank backwards
thru the CO2 line. This raises the water level in the yeast bottle,
and when the yeast starts really producing CO2, the now higher water
level allows the mixture to get pushed up the CO2 line into the tank.
In either case, lots of water changes can normally save the fish as
long as it's detected soon enough.
