Knife stone

The stone as we know it from many Japanese natural aquariums....

Knife stones are very bizarre, angular stones. Excellent for designing “Amano style” aquariums and building reef aquariums.
Since these are purely natural products, there may be deviations in shape and color from the images. The stone only hardens the water slightly, which is not normally a problem and is compensated for by changing the water.

Size approx. 10-30cm. Since the stones are quite heavy even for small pieces, we recommend orders of at least 3kg.

Delivery in kilos (as an example: an order quantity of 8 corresponds to 8kg), minimum order quantity 2kg.
