right and my daily alk consumption is only .2-.3 dkh and im prioritizing alk stability. so i guess i will just have to wait until corals grow and demand increases to start dosing enough kalkwasser to significantly raise ph.I know this is an older post, but that amount of kalkwasser is very low. If the goal is pH raising, you might want to add 5 times that amount. Even if all is added instantly, the pH boost is about 0.1 pH unit. Spread it out and the effect will be quite low.
