[glow=Brown, 2, 80%]First, Craig, I would compare kalkwasser to Reef Complete (comparing apples to apples). Reef Calcium is the polygluconate complexed calcium and it really would be difficult to compare it to kalkwasser (apples to hand-grenades).

Second, I am not immediately familiar with Julian Sprung's Kalkwasser as a product. What makes it different than regular kalkwasser? Is it regular kalkwasser?[/glow]

[glow=Teal, 2, 80%]If it is regular kalkwasser, then Reef Complete delivers 560x MORE calcium than the same amount of kalkwasser. Not only that, it delivers it in proper chemical balance with magnesium and strontium, which kalkwasser does not do. And finally, it is delivered at pH 8.3, period. You don't have to test it to find out. You can feel confident that it is not going to upset the pH or the dKH of your system as you use it.[/glow]

Does this answer your question? If not, please elaborate and I'll try again. [smiley=smile.gif]
