I have been using slightly less than a quarter teaspoon in my 5 gallon when it dips below 4ppm. I have had it as high as 8ppm or possibly higher, I am not really sure, but the bacteria is chewing through that amount of ammonia every two days or so right now, so I am not too worried about overdosing it. My Nitrites are still super high though, so I am keeping at it. I just keep crossing my fingers every night when I test that my Nitrites will finally drop.
Not that I have a ride to the fish store for fish at the moment, but that is another thread... grumble...mumble...stupid dead car....grumble....
