It's been almost 17 years since we had a fish tank and I'm going to ask a stupid question. I read another guy is is having the same thing happening to his tank. My fish are dying. I bought some cycle nutrafin, and I'm not sure where to put the cycle. Do you put it in the filter or the tank?
I appreciate any help.

HI!
You can pour the Cycle by Nutrafin in the water in the tank or the water in the filter.
Either way it's getting in the tank and you will start to notice a huge turn around in your tank.
Good luck!
