I might have messed up. I think I accidentally dosed too much ammonia into the QT and killed the beneficial bacteria.
I thought I was using the 1ml and accidentally used the 3ml one. Ended up adding 15 ml of pure ammonia which I think equates to more than 5 ppm.
This morning I did testing and I read 1 ppm of ammonia, 0 nitrite and 0 nitrate. Which mean totally uncycle tank. What I am curious is where did the other ammonia went to?
Any suggestions anyone?
I can move some more sponge filters from other tanks but I am worry that might cause a mini cycle for my existing tanks.
Should I just add the new fish in the QT next week regardless, add prime and do very large WC every other day?
Or add the fish to QT or 2-3 days with Prime, monitor for obvious disease, give them a few days to recover then add to DT if no obvious symptom?
Or just float and add to QT?
Also, for the QT, what is the best way to keep it cycle long term?
Thanks
