Seiryu Rock - 1 KG

Seiryu Rock is one of the most sought-after hardscape stones in aquascaping thanks to its crisp blue-grey base colour, jagged surface texture, and natural white calcite veins. A 1 kg piece is useful for building detail in Iwagumi layouts, supporting larger stone groupings, or adding contrast in planted aquariums where structure and depth matter.

This stone gives aquariums a dramatic mountain-like appearance and pairs especially well with carpeting plants, mosses, epiphytes, and minimalist layouts. Because Seiryu is a limestone-based rock, it may gradually influence water hardness and pH over time, which makes it more suitable for aquascapers who understand their water goals before use.

Key Features

• Material: Natural limestone-based Seiryu stone with signature white mineral veining and a rugged, weathered texture.
• Size / Shape Notes: Sold by weight at 1 kg; each piece varies naturally in shape, contour, thickness, and surface detail, making every hardscape setup unique.
• Hardness: Dense and durable rock suitable for long-term aquarium hardscape use when placed securely.
• Safe For: Freshwater aquariums, planted tanks, aquascapes, terrariums, and decorative dry layouts when cleaned properly before use.
• Visual Style: Ideal for Iwagumi, nature aquarium, mountain-style, and minimalist aquascaping themes where sharp texture and tonal contrast are important.
• Colour Character: Blue-grey body with bright white veins that stand out beautifully under planted tank lighting.
• Aquascape Use: Works well as a feature stone, support stone, or transition rock around foreground carpets and midground planting zones.

How To Use

• Preparation / Curing: Rinse thoroughly with clean water and scrub away loose dust before placing in the aquarium. Do not use soap, detergent, or chemical cleaners.
• Placement: Position the rock directly on the tank base or on protective support before adding substrate if using large or stacked hardscape arrangements.
• Water Effects: As a limestone-based stone, Seiryu may slowly raise KH, GH, and pH. Monitor water parameters if keeping soft-water fish, shrimp, or sensitive plants.
• Layout Tip: Combine multiple sizes of Seiryu stone for a more natural composition, with one dominant stone and smaller supporting stones placed at similar angles.
• Planting Tips: Excellent for use with Monte Carlo, dwarf hairgrass, Anubias, Bucephalandra, Java moss, and other plants that highlight rock texture.
• Care Tips: During maintenance, gently brush off algae or debris during water changes. Avoid dropping or shifting heavy rocks once the tank is filled.

Seiryu Rock is a favourite among aquascapers because it creates a clean, premium hardscape look with very little effort. If you want bold texture, natural contrast, and a professional planted tank feel, this 1 kg Seiryu stone is a practical and attractive choice for both new layouts and established scapes.
