Awesome Stuff!
I use these to keep the toilet bowl clean and help to sanitize it without much work on my part because of the busy schedule. It definitely keeps the algae from growing in the bowl and also keeps the ring from forming too fast as it does without the Clorox tablet in the tank. What about the environment? Well, I have heard that as it mixes with the organic material from human waste it gets converted or consumed if you will for the lack of a better term into something more mundane that does not damage the environment. Sewage treatment plants that process sewage outflow monitors bacteria in their outflow and adds chlorine accordingly to it to mitigate the situation. Don't believe me? Go to a sewage treatment plant and ask. I did an oceanography study on sewage outflow into the ocean and one of the criteria was to visit a sewage treatment plant to see how their operation ran. As far as ammonia from biodegrading human waste mixing with chlorine to produce chloramine vapor which also has the potential to form hydrazine? Well, for one thing the chlorine keeps human waste from turning into ammonia in the first place because it doesn't "rot".
