I got these delivered from pier aquatics.Great stuff, thanks for the info. Can I ask where you got them from?
The thing is I have no idea, I’m sure I didn’t touch anything but must’ve knocked something somewhere to be able to gas a 400l tank in less than a hour.Which part of the reg did you accidentally knock and adjust, the needle valve itself? Or the control knob that adjusts the second stage outlet pressure?
I asked myself the same question a while ago when I had a similar near miss and couldn't find any conclusive answers about it.Can what happened cause any long lasting damage to the fish?
Same for me, no CO2 ever........... CO2 has been removed never to be used again. The ridiculous thing was I was debating getting rid of the C02 before I replaced the bubble counter. It’s just not worth the risk, there are so many special species in that tank............
That’s good to hear. The fish seem fine today and the added flow from the power heads and air stones seems to have set the corydoras into breeding mode. Crazy seeing that they seemed as if they were near death last night.The only crumb of comfort I can offer is that its been almost 3 months since I gassed my fish and they all appear to be healthy, the corys still regularly spawn and the glass cats which were particularly affected go about there business as normal.

This was a double with plenty left in the tank so it was definitely a mistake somewhere by me.I am guessing that it’s common knowledge here, however, single stage regulators, do not maintain constant pressure, as the cylinder pressure drops, the pressure delivered by the regulator can rise considerably
Well fair to say one of the biggest fish keeping disasters I’ve ever had was narrowly avoided last night.
I broke my bubble counter the other day so had to replace it with new. The bubble count was always high on this tank due to the size but I must’ve knocked the regulator and adjusted it further without realising. I left the tank for around an hour or so and came back to complete carnage. Fish all across the surface, others spiralling and corydoras all on their backs motionless. I thought I’d killed the whole tank. Proceeded to change water as fast as I could and add extra air pumps and raise the filter outlets. This seemed to do the job and it appears I saved everything apart from one cardinal tetra in the nick of time. Everything seemed ok this morning but the dicrossus seemed to struggle more than others and looked dead at one point so need to check on them.
Can what happened cause any long lasting damage to the fish? I feel awful and I would packed it all in last night if I didn’t save them and I’ve been keeping fish non stop for around 20years or so. CO2 has been removed never to be used again. The ridiculous thing was I was debating getting rid of the C02 before I replaced the bubble counter. It’s just not worth the risk, there are so many special species in that tank. Some that have only made it to the uk a few times so I can’t afford for any more mistakes like this. I’m extremely lucky.
Cheers
Something similar happened to me last Saturday. When I do water changes after CO2 has started but before light goes on, I usually crank the CO2 a full needle valve revolution for 5min, tops 8min after I do the WC. This is to replenish CO2 in water just before lights go on. Well, I forgot to bring the needle valve to its baseline position. This was only 5 minutes extra from what I usually do. The rasborras and the ottos where already at the top of the tank looking for oxygen. Was lucky I caught it in time and no one died.Its a good reminder to anybody reading this that when things go wrong with co2 it happens quickly and can often be catastrophic.
It’s crazy how fast things can turn with C02. My incident was probably less than half an hour in a pretty big tank with surface agitation and everything was nearly dead!This was only 5 minutes extra from what I usually do.
