Gassed almost all my fish.

So I come home from work today, go to feed my fish and their almost all floating or stuck to the filter. What happened was the co2 line popped off the diffuser and pumped straight into the thank. I quickly put in an airline and did a water change. So far I've scooped out close to 50 fish and I was just telling myself I need a new co2 diffuser

Well, the purpose of the diffuser is to make co2 dissolve better so you use less. If you had higher co2 levels without it something else would seem to be off.

When the diffuser pops off it goes from like 10bps to like 1000 bps since now there's no back pressure.

Sorry to hear. That can be really disheartening to keep going in the hobby.

I'm not all too familiar with co2 set ups, but this sort of co2 dump is only possible with in-tank diffusers right. Besides a "end of tank" dump. Something like a external reactor or inline (out of tank) atomizer could come off and dump into the tank. But I guess it would dump into the house.

What if a full 20 lb tank dumped into a average size room with no ventilation, is that very dangerous or deadly to humans? If so, what size tank could fully dump and still cause no harm to humans (5lb. 10lb,etc)?

Thanks everyone, I think there's maybe 20 doing better or fighting for their lives. So heart breaking to come home an see that. If I only checked out my tank as soon as I got home I might have been able to save more. I'd i have a co2 controller would it have shut off the co2 ? My ph was at 5.4 when I checked. Normally I have if drop to 6.5-6.7

Makes me want to switch to a cerges reactor even more now.
Off to Home Depot this weekend. This post has helped me put a bigger priority on building the reactor.
Sorry to hear about the losses.

Man, this really bums me out for you. I've lost a couple of fish recently due to dumb mistakes and I know how that made me feel. I can't imagine how you feel after all of this. Keep with it though, this hobby can be so rewarding.

Oh I love this hobby, I've had tanks since I was 5. I got out of it for a few years and came back over a year ago now with a planted tank. Still learning and going one third tank now I'm just scared to turn on the co2 again while I'm at work lol

I've read that you should run an air stone to provide O2 for the fish when running CO2. Anyone have thoughts on that?

I added air after reading that (I have a DIY CO2 setup) and my plants started pearling.
