Buying Guide

Match substrate to tank type

Choose clay-based or nutrient-rich substrates (good for planted tanks) versus inert river or pea gravel for decorative or shrimp-friendly setups

Check particle size

Finer gravels and flour-like clay promote root contact for plants, while larger pebbles improve water flow and are easier to clean

Consider pH and chemistry

Select neutral or inert gravels for stable pH; specific plant-focused substrates often help root nutrition without altering water chemistry

Think about aesthetics and scale

Natural river rocks and colored clay gravels create different visual effects—match color and grain size to fish size and tank theme

Evaluate weight and layering

Heavier clay gravel like flourite holds plants better and supports layering with sand or root tabs, while lighter pebbles may require planting aids
