I used this for my science fair project. i tested to see if the tds actually decreased when you put it in but it doesn't. did i do something wrong?

The majority of TDS are going to be calcium and magnesium, and the advert specifically says those are left in the water, so you might not expect TDS to decrease by much.

Is it ok to use these in stainless steel water bottles? Does it react poorly with the metal?

Kishu does not react adversely to any type of vessel material. Thank you for your inquiry!Judith Bershof/Founder of Kishu Charcoal

Does this work for vodka?

Hello Stranded -It is possible to use Kishu in a variety of ways. We have not yet marketed it for alcohol-enhancing purposes although it's in our testing protocol.Thank you for your inquiry.

How long does it take to filter the toxins in a bottle of water?

Kishu begins working immediately. Optimal filtration takes 2 hours.Thank you for your question.
