You may want to try lowering the Alk to 7 - 8dKH range which is typical for natural seawater. Make sure your test kit is accurate as well.

I found that once a tank starts doing this it won't stop until the Alk is lowered. Increasing the magnesium does not help either.

Hope that helps.

Cheers,
Tim
