Property me from this hole rock not the Asian variant shown here, but the same article, however, ordered a perforated rock Yugoslav. Unfortunately, I can no longer find this product, but the provider and price / kg stones are almost identical. Arrived in my package a quite beautiful stone, specified weight of 1kg fit well, color was a little more into the yellow / orange, as in this Asian variant. The surface was a little bit of crumbly that could be changed with a cleaning under running water but quickly. Before placing into the aquarium I cook all items va stones always from above for any germs to remove. What can not, unfortunately, could be removed, was the pungent smell that gives this piece of rock, unfortunately, into the aquarium water. Clouding not caused the stone though, and the many fish in my 125l fresh water pool seems to mind the smell, but I find him to be very uncomfortable. A partial water change I've already done 2x, so now could not really change up. Airs now regularly by opening the flap and hope that it sets itself. Otherwise purely seen from the optics a nice decorative element.
