Mrs. Wages pickling lime is essentially generic kalkwasser. You'll find it in the canning section of some walmarts and also at most country general stores.
agree w/the seachem reef advantage calcium. I also have a oolitic dsb and rarely need to add calcium(at least not the recomended amount) anymore. I hold steady at 450 but some people dont like the dsb so reef advantage it is.its a powder that long outlast the liquis . much more cost effective IMHO
Prestone driveway heat is working great for me! I use it to get my calcium levels where I want them, then dose Kalk in my auto top off. Working like a charm so far.
