Bacterias (most of them) can't live in acid too and drinking alkaline water has no impact on your bodys acid-base-level otherwise some of your organs would have problems working proper (that's why there a many mechanics to keep your ph-level in a very small range). And afaik alkaline water costs a lot more than normal water.

Short version:
No effect and high costs.

It can’t prevent all bacteria and there is certainly good bacteria and bad bacteria. Our bodies are never completely alkaline due to our environment and the things we consume. I’ve seen it happen in myself , my body is more alkaline after drinking this water.

No, your body is not more alkaline. This would cause several organs to have problems.
There are many ways our body controls this stuff. And that's a reason why it is not wise to mess with this stuff.

The beautiful thing is we can respectfully agree to disagree.

Right.
As long as you want to waste your money. Go on.
I just hope that you don't "inspire" other people to try this.

The only thing I ever “inspire” ppl to do is their own research and to think for themselves. Also, I’m not wasting my money. My alkaline water is provided to me at no cost to me. I appreciate your concern.
