Fluval Betta Stratum 800g

Fluval Betta Stratum 800g – Volcanic Substrate for Betta & Planted Aquariums

Sourced from the mineral-rich foothills of Mount Aso Volcano in Japan, Fluval Betta Stratum is a nutrient-rich volcanic soil substrate infused with beneficial bacteria. It’s purpose-built for betta tanks, with a granule size and texture that’s gentle on delicate fins while still holding up well in planted setups.

Each granule measures 1 to 3mm, small enough to keep food accessible to your betta without disappearing into gaps, and smooth enough to avoid snagging or tearing fins. One 800g bag covers up to 10 litres of water. Pairing it with a proper diet? Our Hikari Betta Bio-Gold is a great match for daily feeding. Setting up a larger planted tank or shrimp colony? Our full-size Fluval Stratum range comes in 2kg, 4kg and 8kg bags.
