I had my progold for over a year now. I keep it in a dark and cool place underneath the tank. At times I smell it and it seems fine like the same day I received it in the mail . I looked through the forums and I found all different types responses from other members. some say 1 year or 3 months ... etc..

anyway I guess what i'm looking for is for someone that has progold.. how long do you keep it before throwing it out?

thanks

Hi,
Since Progold is expensive and the smallest quantity lasts me longer than 6 months, I will guess that it is good for at least 6 months, maybe longer, especially when it is in a cool dark place. I keep mine in a drawer.

You could go to www.goldfishconnection.com and email Rick--ask him how long it lasts.

thanks for the advice
