And, if you really wanted to, you could decorate the bottle to make it look a bit pretty, like glue a fake duck on top.

I would never put chlorine tablets in my toilet tank again. Even in a large pill bottle with the smallest holes drilled in it, still ate any rubber seals and metal in the internals within a matter of weeks. (The bowl was, however, the cleanest it's ever been LOL).

GREAT to wait for Memorial Day. Right now the pool is under 3 feet of snow and ice!

That is an interesting idea. Do you think that you could make a small one out of a 20 oz soda bottle and use it in the toilet tank. This might keep the toilet clean and using the cheaper pool chlorine tablets than the expensive toilet chlorine tablets?
