Pure Water Pebbles salt and pepper aquarium gravel in 5 lbs, a natural speckled gravel for small tanks.
Aquarium gravel is a durable, inert substrate that never breaks down and gives roots a stable anchor, making it a practical base for many planted tanks. Because it holds no nutrients on its own, gravel pairs best with root tabs for heavy feeders and liquid dosing for water-column plants. Grain size matters more than it seems: too large and fine roots struggle to grip while debris sinks into the gaps, too small and it can compact. A medium, rounded grain usually strikes the right balance for both plants and easy cleaning. This substrate suits hobbyists who want a long-lasting, low-cost foundation and do not mind supplementing nutrients themselves. It is forgiving for beginners, easy to vacuum, and available in many natural tones that complement wood and stone. If you keep hardy rooted plants like swords or crypts, or you want a bed you will not need to replace in a few years, gravel is a dependable and flexible choice.
