This is a good solution to making my home safer but in an ordinary house I find it difficult to use contents of bottle in 48 hours. I had not realised I then had to dispose of rest. Next time I will break tablet in half and do same with amount of water. Even then not sure how much I will end up throwing away. This aspect wasn’t really clear when I purchased. Maybe you could come up with a smaller tablet for the future.
When I have used current supply I will look and see.
