Could shrimp pellets or some of this finely ground ADF food work as well as a snail at keeping the bacteria fed? The guy at the petstore said to try frozen shrimp, as in the kind people eat. I have no idea how to take that advice.

I MAY be able to get an apple snail or two or some ghost shrimp. The problem is my Nitrites seem to be way too high to really house anything.
Until then fish food/frog food? I want to get away from the chemical as well, but it was recommended on a fishless cycle (although they do say that in a pinch some food will do.

Should I continue to do this advice or go with Carlos?
I personally, would like to move them, as I think space may be the biggest stressor of all.
