## Long description

Gravel stones Ultimate Products Tumbled Blue Ocean 30–50 mm are decorative tumbled stones sold in a 10 kg pack, intended for aquarium and terrarium use. These stones are rounded and smoothed to sizes between 30 and 50 mm, providing a stable substrate layer and a natural-looking blue tone that enhances tank and enclosure aesthetics. The stones support plant anchoring, create visual contrast for aquatic life, and form solid footing for reptiles and other terrestrial animals without sharp edges.
Advantages
The tumbled finish reduces dust and sharp points, making the stones safe for both aquatic and terrestrial environments. A consistent size range (30–50 mm) ensures even coverage and predictable layering during layout. The blue coloration delivers long-lasting decorative effect without the need for additional dyes or coatings. The 10 kg pack offers sufficient quantity for medium to large setups and simplifies substrate replenishment or redesign.

How to use
Rinse the stones thoroughly under running water before first use to remove any residual dust from packing and transport. Spread an even layer across the bottom of the aquarium or terrarium to the desired depth, taking care to create slopes or focal areas as required by your design. For aquariums, combine the stones with filter media and planting substrates as needed; avoid placing very fine substrates directly on top of the stones to prevent clogging. In terrariums, arrange stones to create stable basking areas and drainage layers beneath soil or moss where appropriate.
Usage recommendations
Inspect stones for foreign matter and rinse again periodically during maintenance. When used in aquariums, monitor water parameters after installing new substrate and perform partial water changes until clarity stabilizes. Avoid using chemical cleaners or detergents; plain water and a soft brush are sufficient for routine cleaning.
