If you have had success with Kalkwasser, you will have the same results with PICKLING LIME.
It is the same stuff. The cons are that it tends to be a little coarser and as a result does not dissolve as well. My LFS sells a jar of Kent Kalkwasser for $15 for a container the size of a Noxima jar. I can buy a 1lb bag of PICKLING LIME for $1.67 and they are the SAME THING. Not sure what it costs at Wal*mart.
Get past the name.
I am just passing along some info so other hobbyists like me who are on a tight budget can still function. I can give you links to other sites where ppl are successfull using PICKLING LIME.
Do a search on yahoo using pickling lime and kalkwasser. You'll get tons of hits, read other ppls experience with it. If you decide to dose with Kalkwasser, I would recommend at least trying it.
No I don't use it yet, because I don't need it yet. When I do I will be building a Kalkwasser (Nilsen) reactor and using PICKLING LIME instead of Brand X.
