why do i need 150 of them?

Well, it's a matter of personal choice. I test frequentl, so I am happy there are 150 of them. The box that I just got doesn't expire until August of 2023, so I know I will have no problem using them by that time. I like to make sure my water softener is working.

Can it test bottled carbonated water?

I am sure it can. I would test the freshly opened bottle first, then let it stand overnight to lose the carbonation then test again to see if there was a difference. The stale water test should be considered definitive. I am a chemist.

It says for testing magnesium, I don't see a magnesium scale? Does it actually test magnesium?

It tests for it, it tests for all the minerals and metals it lists. It does not have individual scales for each one.

Does this work for salt chlorinated pools?

Yes, it will indicate the total hardness (amount of CaCO3)
