## Long description

Washed red decorative stones from hau & miau, grain size 20–30 mm, supplied in a 10 kg bag. These natural stones are intended for use as substrate or decorative gravel in freshwater aquariums, paludariums and terrarium enclosures. Pre-washed to reduce dust, the stones provide a stable, inert ground cover and add a consistent red tone to the habitat without altering water chemistry when rinsed and used as directed.
Advantages
The stones are pre-washed to lower suspended particles and minimize initial clouding in water. Their 20–30 mm grain size creates a stable layer that supports plants, decorations and hides while enabling water flow through the substrate. Made from natural material, the stones offer long-term durability, low maintenance and consistent colour for aesthetic improvement of aquatic and terrestrial setups.
Suitable for
Freshwater aquariums as decorative gravel or substrate top layer
Paludariums and vivariums to create natural-looking shorelines and dry areas
Terrarium floors for reptiles and amphibians where a coarse, stable substrate is required
Plant displays and decorative bowls that require inert, coloured stones
Key specifications
Grain size: 20–30 mm
Package weight: 10 kg
Colour: red (natural stone tone)
Finish: washed to reduce dust
Material: natural stone (inert)
How to use
Before use, rinse the stones under running water until the rinse water runs clear to remove any remaining fine particles. For aquarium use, add a layer of stones to the chosen depth suitable for your setup; avoid covering filter inlets or blocking water flow. In terrariums and paludariums, distribute the stones to form stable walkable areas or decorative borders. Monitor water parameters after installation to confirm no unexpected changes occur.
Usage recommendations
Rinse thoroughly before placement; combine with appropriate substrate layers when keeping live plants or burrowing species. Do not use with species that require very fine substrate for digging or egg deposition without additional suitable substrate. Regularly inspect and clean stones during routine maintenance to prevent detritus buildup.
