Did a water change Friday the 4th and now I have alk at dkh of 17, ca at 390 rising it slowly dripping kalk, ph at 8.3, any suggestion as to how to get alk down without affecting ph and ca much. Never been able to get it down below 11 dkh.

Not sure if you've seen this article, but it's THE one (in my opinion) for fixing ca/alk imbalances...
