This wasn't EOTD the OP stated they forgot to turn their CO2 off. By all accounts EOTD is rare.

Sorry to hear OP, little late but I'd suggest a timer so you don't have to remember every night to shut it down.

SlabMonster Thanks. It's a little scary how quickly it happened. Makes me nervous about my single stage regulator and the dreaded end of tank dump.

Kntry I'm glad you saved them. I did the same thing about a month ago, trying to edge up the CO2. Tons of air and 75% water change saved them.

SlabMonster I just had a terrifying experience with my 29 gallon! The timer on my solenoid turns on at 2:15pm, my lights turn on at 2:45pm. Earlier this morning, I was fiddling with my needle valve, and I guess didn't crank it back down enough. At 3:40pm I look over to see one of my crystal red shrimp down on his side aimlessly waving his legs. I tried to fish him out, but he swatted himself under a log. At 3:45pm, I notice two more doing the same thing. I would understand losing one shrimp, but three?

I immediately pull them out and put them in a container with some highly oxygenated water from my hospital.. uh.. bucket. I have a 5 gallon tank that was set up just a couple days ago, so the bucket was the best way to not poison my fish. The hospital bucket houses my beautiful German Blue Ram, who was attacked by a horrible silver molly that came with the 29 gallon tank a few months ago. (If anyone in Tucson wants her, let me know, right now she's cycling the 5 gallon tank.)
As I finish pulling out my third shrimp, thinking that there's a parasite or bacteria, a fourth one lands on its back too. Now I'm really freaking out. And all my fish are at the surface...

The CO2!!!! expletive Expletive EXPLETIVE!
I turn the CO2 off and fish out my other shrimp. I grab Pepe, the most peaceful dwarf puffer in the entire world, who was passed out in a corner, and toss him in the container with my weakened and near dead CRS.
I did a 10% water change, grabbed the air stone from the hospital bucket, and tossed it into my main tank.

Within 10 minutes the shrimp were all standing correct again, and Pepe was swimming along peacefully.

They're all back in the main tank now, at 5:30pm, looking much better and eating again. It was almost a disaster. My heart rate finally went down after many drinks of sake and watching them all eat and swim around normally. Funny, the crisis is the only time I got to see my blue velvets at all, as they swam around frantically in distress.

fusiongt It's worry some that you're trying to turn off the c02 by hand every night and on every morning? That's more work than owning a dog lol. Open up the wallet and get a timer (and solenoid if you don't have one) and have c02 as one of those "set it and forget" setups.

But like others said, the real problem is probably your c02 is too high if it's killing your fish at night when plants are producing oxygen. There's no reason for it to be that high; it should be able to run 24/7 without killing them. I prefer to save the c02 so I time it so it's on when the lights are on, but even if I run it 24/7 at that level my fish are fine. (Shrimp on the other hand I have in a low tech tank)

shrimpedout Well at least know suffocating isn't painful, just scary, especially for a fish. I'm glad most of them made it tho!

Get shrimped out!

senior el roboto My co2 runs 24/7 also and no problems there. All my discus, rams, tetras ans coris seem to be just fine. I did almost gas everybody one time. Came home from work to find the valve had been opend up way further than it needed to be. My checker was bad yellow. All fish huddled on the ground gasping. Airstones and water changes later everyone was back to being happy.

C.Barb. Yea I've done that a few times on accident . Haven't lost anything thank god .... I have a blue ram who seems to be more sensitive than all my other fish ... So in order to accommodate him I run my co2 less .

Java Moss Let that spraybar splash the water's surface real good. Can never have too much of that, IMO.

My toddler got a hold of the timer that runs the CO2 solenoid and it was running full time without my knowledge a while back. Water was foggy, plants were bubbling like crazy, yet no deaths or fish freak outs. It was the spraybar that held down the fort!

And yes, he got popped on the behind for that little caper. Told the tyke a hundred times to "stay outta there!"

oscarsx This is my concern and worries also, I always have my powerhead pointing towards the top of the tank for extra water movement

pejerrey I also believe that with good aeration by surface agitation by a spray bar or surface skimmer or an airstone.

This thread is a good read to understand why we can suffocate our pets:

Next time, take seriously the fact that you can kill them. Choose a way to do it that is not at the edge of a catastrophe.

My condolences.

HD Blazingwolf co2 is the killer

the silent killer is oxygen levels
i firmly believe this and this is why i happily run my wet/dry sump setup now. i inject what on my cannister would have been lethal, now only is slightly stressful if i make a mistake
its still possible to kill my fish with co2, but i have more room for error, and its VERY apparent. GOOD surface agitation and clean filters, plus good water chagne habits and happily growing plants will rpevent many of these problems
for reference, my dc is yellow 2 hours after co2 is on, not by the end of the light cycle. it stays that way all day, and when i get close to end of tank my working pressure increses 2-5 psi depending on ambient temperature and fish still are fine

It depends on the amount of CO2 you are injecting. What is the color of your drop checker? Mine is deep yellow by the end of the light cycle. 24/7 CO2 on my part without at least an air pump at night? I will see dead fish in the morning for sure.
