How do you lower the alkaline level?

[quangtam7]

[My alk is around 15 dkh and calcium ~ 380 ppm, raising calcium level is easy but how do you lower alk? Fishes and corals are fine at this point.
Thanks.]

[Stop adding any type of Alk additive, and it will be dissipated over the next few days. And if you are using Tap water, you need to switch to RO/DI. My dKH used to be 23 before I switched to RO/DI.]

[There are different ways of adjusting just water chemistry. Please list your tank water's parameters to better understand where you stand and what measures can be taken to solve the problem.]
