Well, I first added some floss from my filter in the office tank and thought that would spur the bacteria on. No drop in the ammonia from that (steady at 4ppm).
Then, when I changed the water in my 75 gallon,
I removed a bunch of K1 filter media I have in an Aqua Clear 110 that I have on the back of that tank and switched it out with some of the media in the filter for this tank (the 75 gallon primary filter is FX4- I just have the AC110 on the back as backup). I also took 5 gallons of water out of the tank upstairs, squeezed the sponge from the AC110 into it and add it (and the detritus) to this tank.
I thought for sure the next day the ammonia would drop, but nope. Two days later and there's no change.
Why can I take a sponge filter from a working tank and plop it in a quarantine tank and it work fine, but when I add all this stuff that most surely must have beneficial bacteria in it to this new tank, it doesn't immediately start eating up all the ammonia?
The ammonia comes from Dr. Tim's and it is still reading about 3ppm - it dropped from 4ppm, but I changed out 5 gallons of water as noted above, so that's why.
I'll wait like a good little fish keeper, but dang, what am I missing here? Does this seem unusual or pretty standard?
