    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.

    Does anyone know how much 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?
