Thanks Alton, I've done that and it's not enough. So testing again to see what drop I have. I'm still using the kalkwasser though.

Kalk is equal parts alk and ca, as I understand it (and used it myself) as something to maintain levels, not raise them. I think I may have mentioned it in a previous post, but 360 for ca is low, I'd bump that up to at least 400. Bring both ca and alk to your target numbers, test again 24 hours later and see if they drop or not. If they don't, then your kalk is doing its job.
