Quick Answer
Aquarium gravel is easy to clean and works for many beginner tanks. Grain size matters: very sharp or large gravel can trap waste and may not suit delicate bottom dwellers.
Care and Setup Notes
- Choose smooth gravel if keeping bottom dwellers.
- Vacuum sections instead of disturbing the whole substrate every time.
- Avoid painted gravel if chips or coating quality are questionable.
