Massive fish kill in my tank!!

[Airgoose2222]

WTH!!!?!! My water was getting low in my tank, so I added about 6-8 gallons of water. Used the same bucket I always do, added a little chlorine remover, and that's it. Three hours later, the fish look like this...
How on earth does this happen?? I've had these fish for years and try even survived a move from Oklahoma to Colorado in a cooler. This is nuts! I'm ticked and sad at the same time. Don't even know what to do here..

i dont know maybe there wasn't enough chlorine remover or there was an large amount of ammonia

I don't know. It's a 135 gallon tank. I couldn't imagine 6-8 doing such massive damage in only a few hours. Nothing changed in the readings either. Very odd!

Maybe something in the bucket?

Maybe something in the bucket?

+1 some other liquid that wasnt noticed when you put water into it? Also do you have your params?

Okay, now this is a miracle of all miracles. You can see in the pics that these guys were dying and sadly one actually did, but I was thinking maybe something with the oxygen was jacked up. I took a big bubbler from another tank and added a quick spray bar to it and now everybody is happy and swimming normally. Very odd how suddenly the oxygen was depleted, but glad I guessed right the fish that died luckily wasn't one of my favorites, but he was still part of the "family". I'll definitely check the bucket next time too. Very weird

I think using too much prime actually causes a lack of oxygen so maybe that's a possibility

Awesome, I'd hate to see a nice tang tank die off. Did you bump a power head creating surface agitation or something on accident?

Do you do water changes or just top off for evaporation?

+1 how much did you add? I almost always underdose. Like if I take out 100 gallons ill only treat 50 gallons of it.
