I just did a 70% water change and the only thing I did different was i forgot to use Prime as I was refilling. I let for about 10 after finished, and when i came back, all my fish are laying on the bottom of the tank breathing heavily?????
I quickly added a double dose of Prime, and 10 min later there has been no change, what else can I do and why did this happen????
I change the water every week and this has never happened???
HELP
