Overview:

WIO Titan Boulder Mix is a premium natural hardscape stone with a distinctive grey-bluish-green colour and striking white layered markings. Its rounded boulder-like form gives aquascapes a softer, naturally weathered appearance, making it especially suitable for Iwagumi-style layouts and clean, minimalist aquascapes.

This metamorphic stone has a smooth yet characterful surface that reflects light beautifully underwater, helping to highlight its natural tones and layered structure. Its rounded shape makes it ideal for creating calm, balanced compositions while still adding strong visual interest to the layout.

As an inert stone, Titan Boulder will not alter aquarium water parameters, making it suitable for planted aquariums and safe for fish, shrimp and other aquatic animals when used correctly.
