Shouldn't I be seeing nitrates already?
6 neon tetras inside of 130 gallons with a 40 gallon air sponge filter, nothing else.
After 6 days, the ammonia registered at 0.25ppm, so I inoculated the filter with nitrifying bacteria, enough for a 40 gallon tank, according to the bottle (I did this within a 5 gallon bucket, with the air pump filter running, for about 10 minutes, pouring the water back into the tank when done). Over 24 hours later, the nitrates are still at 0 ppm. The ammonia appears to be climbing still.
Do you think the nitrifying bacteria bottle was bunk or is there an issue with the other specs I'm playing with?
