I am doing a fishless cycle on my 37g right now. To seed it, I put 2 bags of gravel from my established tank under the filter intake tube. I also took the 3 month old cartridge from my established tank and cut the blue foam/sponge top off of the plastic frame and put it between the sponge and biomax layer of my AC70.
My established tank is an Eclipse System 12, so the filter/cartridge looks like this: (not my pic, I googled it)

As you can see, the cartridge lays flat so the top is exposed to air as the water runs over it. Since I submerged it in the AC70, did I kill the bacteria?
I've read here that the bacteria needs air to survive, so how does it live in the gravel and in the biomax that is submerged?
I am only 6 days into my cycle, but I have been getting readings for nitrites and nitrates since day 2 although neither has spiked. I am adding enough ammonia to keep the tank at 2ppm.
