High Alkalinity compared to used salt.

[Randy Holmes-Farley Verified Community Expert]

Yes, my salinity is 1.026

How can it be right though, when the salt says that its supposed to be around 8?

Try measuring some new salt water. The mix might be off, your fresh water may have alk in it, the rocks in your tank, if artificial, may release alk, etc.

it says that the that the information on the bucket is only "precise" if you're mixing at least 350g of salt. And im mixing 570g when im doing it, so that im not mixing enough salt, is impossible.

Here's the information part of my comment was based on. Your situation is bit more extreme but there could be some cummulative effects with other issues.
