I have ADA aquasoil. O kH and 0 gH.

Its right out of the tap. However, it must also be noted my water is slightly cooler than the average. Around 68-65 which means it can hold slightly more dissolved gasses than the normal room temeperture. So with that combined, I think it draws down my pH a little more.
