Not been tampered with.
Order this 24 hours ago, here already. Last time I bought this product from a different company it came without a foil seal. Nice to see that this company hasn't tampered with it.

I'm only dosing about 250 ml of kalk per day into my 164 gal majority LPS reef, spread out evenly over 12 doses. But even at that small amount, I've seen great stability in my calcium, alkalinity, and pH. This stuff works well, and it's very cost effective. This jar will literally last me more than 9 months. Worth it to spend a bit more for a pure, high quality product, as opposed to food grade pickling lime.
