Does anyone know what is the structure of that stone? Is that a limestone?
When I do a vinegar test it reacts a lot.
Shops even warn that it raises pH and hardness.

I'm not sure you can estimate how much in general it will raise GH/KH.

It's pretty "limy".

It slowly dissolves in tanks.

My tank is 220 g, tap water is KH10 ang GH14, I have 35 kg seiryu stone inside, co2 is 20-30ppm. I do EI dosing and 35% weekly water change.
What do you think how much it would raise the KH in a month?
I know it can't be calculated, but what is your opinion?
