I am a *big* fan of kalk, but it's *not* the only way.


Fair comment I'm sure. I have never tried to do things any other way
myself, though I have heard dealers mentioning other proprietary
products instead. In fact I get mutterings about this every time I
mention kalk to one local guy... I always wondered if that was sales
talk though, kalk is cheap and doesn't earn anybody much after all. So
how well do other things work then? Any advantages over using kalk,
given that Ca and OH seem to be the main things you need to add long
term? Interested in your views. My main point to the OP here though
was that he seems to be doing nothing much other than adding fresh
topup to this tank, and has said nothing about water changes either,
which is a worry. And my own tanks have always seemed to go backwards
as soon as I've had skimmer problems, as has occured in the past, so
I'm a big believer in those.
