Well, after talking to my dad last night I decided to check my ammonia, nitrites, and pH. Everything looked great except for the nitrites, which were at 0.8. This was after I had done a 25% water change earlier, as is my weekly routine for this tank. This doesn't make sense to me, but maybe someone here can help me out.
