About this item

• Color & Tone: Featuring dark bluish-grey with striking white veins, Blue Mountain Seiryu Stone creates contrast as aquascaping rocks or aquarium decor that darken when wet, adding depth to aquascape layouts.
• Texture & Structure: Angular edges and detailed crevices create a rugged, natural look for aquascaping. Stones range 3–10 inches, adaptable as large aquarium rock accents or centerpieces.
• Versatile & Durable Hardscape Material: Complements aquarium gravel, decorative pebbles, driftwood, and live plants. Works in Iwagumi, riverbed layouts, mountainous designs, or aquarium stacking rocks.
• Simple Preparation: Rinse thoroughly before use to remove dust and reveal the stone’s layered detail. As Seiryu may slightly raise pH and water hardness, check compatibility with your setup or consider pairing with aquarium soil.
• Convenient Pack: Available in 5 lb, 10 lb, 20 lb, and 30 lb. For large rocks for aquarium layouts, higher weights provide larger stones—contact our team if you need assistance.
