Alan update me on your Coraline

[Jack Rainville]

Alk is important in your tank not only for the growth of coralline and corals, but also as a buffer against sudden dangerous swings in PH. Think of alk as a reserve for PH. If your PH tries to swing hard one way or the other, alk will be consumed and the PH will stay close to normal. The less alk you have, the more the PH will be allowed to swing away from its balance point.
