Yes. I had this happen once before, except the problem was because
some weird gelatin formed over the airstone and blocked the air flow.
The place where the airline was siliconed to the cap of the 2 liter
broke, and a fountain of foam covered my ceiling 6 feet above
it...just a little pressure buildup.
I have a problem that I'm hoping someone can give me suggestions on.
I've had all the fish in my tank killed by acidosis...twice now. Both
times were as a result of massive pH changes due to my inaccurate CO2
The first time, the tank just ran out and the pH went from 6.2 to 7.8
in about two hours.
The second time, last week the whole CO2 tank vented into the aquarium
at once--a one inch shell of ice on the CO2 canister was a bit
I have my CO2 canister, through a regulator, pumped into the input on
my pump. The pump is connected to a 1/2" hosee which is connected to
a PVC pipe with sponges inside (hanging vertically). The water is
forced vertically down into the vertically-oriented chamber with
sponges inside...it slows down the CO2's escape and traps some of the
bubbles in the sponge. I think what happend was that the sponges got
clogged with mulm and during a short power outage, with the pump
stopped, a pressure release event like my yeast explosion
happened--the pressure built-up behind the plugged-sponges eventually
blew the intake off of the pump and vented the entire canister of CO2
into my tank...the pH was something lower than 5.5 (the lowest my kit
will measure) and all my expensive fish (including about 10 siamese
flying foxes which cost $8 + shipping ea.) were floating uncontentedly
It hasn't killed any of the plants yet, but the crypts are feeling the
strain. I haven't had any CO2 in the tank for about a week now and I
really have to wonder what to do.
I won't cope with another mass fish death due to massive pH
fluxuations and I don't think I can afford a fully-automated CO2
injection system--and I won't go back to my old unreliable yeast
method. Isn't there a reasonably affordable reaction chamber
available to help dissolve CO2? Even That Fish Place claimed to have
no such thing. I had to makeshift--and it turned out to be the death
of my fish.
I will no longer keep expensive fish because I can't afford to replace
them. I have two 10 lb. CO2 tanks and a regulator--anything I can do
that will make a reliable system for $100 or less?
Thanks in advance.
