Buying Guide
What should you consider when selecting tropical fish tank gravel?
- Color and lighting: If your tank uses blue LED lighting, fluorescent-accented gravels (like many GloFish options) will glow strongly and create a striking display.
- Size and weight: Choose grain size that suits your filter, plants, and fish; smaller grains work well for planted tanks, while larger pebbles are easier to clean in bare-bottom setups.
- Natural look vs. dramatic glow: Natural pea gravel or river rocks provide a subtle base, while black or white gravels with fluorescent accents offer bold contrast under light.
- Safety and cleanliness: Ensure the gravel is non-toxic, inert, and rinse thoroughly before adding to the tank to reduce cloudiness.
- Maintenance: Lighter colors may show detritus more; consider weekly gravel vacuuming to maintain clarity and water quality.
