sweet i love that kalk its pretty awesome stuff. hmm do you know perchance what your levels before adding the kalk was? how much you added? how much calcium your tank takes up daily? I found this out by testing calc one day then 10 days later when i tested again it was 20 ppm lower. thus i dose w/ the 1 ml per gallon rule b/c the w/ the kalk 2+ it adds 2.3 ppm of calc per gallon per ml of solution added
