Not needless worry. There have been instances where people have died cleaning their bathrooms with ammonia and chlorine bleach. The lethal combination plus lack of ventilation likely caused it. It is not a situation to be minimized.
C'mon man. Everyone knows that mixing straight ammonia and straight chlorine is dangerous. But this is not what the post is about.
Did you read the OP's question and adayjk's reply?. The ratio of free chlorine in tank water to diluted urine Is so small that there wouldn't be enough gas produced to be a hazard. We are talking parts to million of both substances. In addition the tank is vented to the atmosphere.
