I’m not quite sure what kind of test they used. It was not a api kit I know that. I’m gonna do a 20gallon water change and add the fritz and hope that helps. Really appreciate all the helpful people.
1 1.5ml seems like not a lot. The bottle saids 60ml per 5 gallons established system or should I listen to you ? Thank youYou can add fritz at 1-1.5ml per 10 gallons after you do a water change which I agree with. Do you happen to know what test kit they used? If Api, , I am not comfortable with those numbers
