It turns out that the cause for the ammonia (which is between .25 and .50) is the fact that I was a big enough tard monkey to leave DEAD CRICKETS at the bottom of the tank. You see, I had my mantis living in there so he wouldn't fly into any other rooms. I frequently dropped crickets in there for her to eat, and she would leave in remains such as the head, wings, reproductive organs, some parts of the body that she just didn't want, and all that. When I was putting the gravel in the tank, I was thinking "DOHOHO THE CRICKETS WILL BE UNDER TEH GRAVOEL SO THEY WON"T TOXIFY THE TANK" But boy was I wrong. About a week, later, I totally forgot about the dead crickets in there and filled it right up. Eventually for some reason, I added the bacteria and they didn't do anything. This is probably because they weren't too deep in the gravel. So, I'm gonna remove the crickets after I get off my lazy but and I'll put the bacteria deeper into the substrate. Is this a good idea?
tl;dr: I left crickets in tank, crickets cause ammonia, ammonia spike.
