## Summary description

Hau & Miau Kamienie MIX is a 5 kg pack of washed natural stones sized 10–20 mm for aquarium and terrarium use. Suitable as substrate, decorative gravel, or ground cover, these stones provide stable footing, support planting and filtration, and help create natural-looking habitats for fish, reptiles and amphibians. Ready to add without further rinsing.

## Long description

Hau & Miau Kamienie MIX 10–20 mm are natural washed stones supplied in a 5 kg pack for use in aquariums and terrariums. The rounded 10–20 mm gravel creates a stable substrate layer that supports plant roots, improves water circulation around the base, and contributes to a natural aesthetic in both freshwater and reptile environments. Stones are pre-washed and ready to use without additional rinsing, making them practical for rapid setup or maintenance tasks.
Advantages
The gravel consists of mixed natural stones sized between 10 and 20 mm, offering good stability under plants and décor while reducing shifting compared with finer substrates. Washed surface reduces initial turbidity and minimizes the need for prolonged flushing. The neutral appearance integrates with different aquarium and terrarium styles and does not contain added dyes or coatings, making it suitable as a base layer for filtration, planting, or decorative cover.
Suitable for
 Freshwater aquariums as a substrate layer or decorative gravel
 Terrariums and paludariums for reptiles, amphibians and terrestrial plants
 Planted tanks as a base layer beneath finer substrate or root tabs
 Decorative ground cover in bioactive enclosures
 Stabilizing heavy décor such as rocks, driftwood, and caves
Key specifications
 Granule size: 10–20 mm
 Package weight: 5 kg
 Material: natural washed stone mix
 Surface: rounded/smoothed by washing
 Color: mixed natural tones
How to use
Distribute the stones evenly across the bottom of the aquarium or terrarium to form a stable substrate layer. For planted aquariums, lay the gravel as a base layer and add a finer plant substrate on top if required. When arranging terrarium landscapes, use the stones to build slopes, drain layers, or to anchor décor items. Although the product is washed and ready to use, it is acceptable to perform a quick visual check and remove any fine dust with a brief rinse if preferred.
Usage recommendations
Place a suitable separation layer between the gravel and any very fine substrates to prevent mixing. Avoid using in systems where sharp-edged stones could damage delicate species; choose rounded pieces for enclosures with soft-bodied animals. Regular siphoning during water changes will help keep gravel clean and maintain water clarity.
