Buying Guide

Check inert material composition

Choose rocks advertised as non-reactive (e.g., natural river stones or polished pebbles) to avoid altering water chemistry

Match pebble size to tank inhabitants

Smaller gravel is better for planted tanks and small fish, while 1–2 inch stones suit larger tanks or decorative layouts

Inspect surface finish

Polished pebbles are smooth and fish-safe; rough or sharp-edged stones can harm bottom-dwellers and delicate fins

Consider weight and coverage

Calculate pounds per gallon needed for stable substrate and anchoring plants—heavier river rocks require more support

Avoid dyed or coated stones

Steer clear of brightly colored or coated decorative pebbles unless explicitly labeled aquarium-safe to prevent bleeding dyes
