Can you add bleach to the water to prevent mold?

Hi, yes you may, although it is bad for the environment. We suggest vinegar + baking soda, that works too but whichever you prefer.

How much pressure can it take? Like could I bear hug it as hard as possible without popping it?

I can't, but if you think you can, you got 30 days to try, that might be covered by their warranty.

What is the kettle tank?

so, this item you are asking about has not actually been available yet. However, if you were to deduce it was a smaller version of the tank sort of in a kettle bell style, I believe you would be correct.
