Anyone have horror stories about using Kalk

[Doug]

Thanks Brad. I forgot the others, like 2-part. Like he says Michael, if your demand is not to high, then something like ESV B-Ionic is ideal. Every morning or so, you just dose an equal part of each. I use to use 35ml of each per day in my 70g soft coral tank, that had lots of coralline growth.

I dont thing were hijacking Brad, Just adding more info. Perhaps I will start another.
