ADA KUMU Ohko Stone ST-02 250g - 30~80mm The ADA KUMU Ohko Stone is a classic aquascaping material from the KUMU Layout Series, valued for its warm, earthy tones and highly textured surface. Often recognised for its intricate holes and weathered contours, this stone adds immediate character and natural complexity to any aquascape. With pieces ranging from 30–80mm, Ohko Stone is perfect for adding detail and refinement to your layout. It works beautifully as a transitional material between larger feature stones, for building layered foreground interest, or for enhancing midground depth. Its irregular structure creates natural shadowing and contrast, helping to produce a more organic and established look within the aquarium. The porous surface also offers functional benefits. The many crevices and cavities provide ideal grazing areas for shrimp and small fish, while contributing to a more biologically active hardscape. Water Parameters KUMU Ohko Stone has minimal impact on water chemistry compared to many decorative rocks, making it a dependable choice for a wide range of aquariums. While minor changes in hardness can occur, it is generally well suited to both planted tanks and community setups when regular maintenance is maintained. Versatile by Design Although most commonly used in Nature Aquarium layouts, Ohko Stone is equally at home in paludariums, terrariums, and smaller decorative compositions. Whether used as a supporting texture or as a focal detail element, it brings warmth and natural structure to your aquascape.
