I recently switched my substrate to sand. I’ve heard of poisonous gasses that build up in the sand and today I sort of stirred up the sand a little and there was some bubbles that came to the surface. Could someone please explain to me if that was the gas I’ve heard of, how often to stir it up, or just what I might need to know and do about the poisonous gas?
