Fluval BIO-STRATUM Substrate for Planted Aquariums – 3 Sizes
Collected from the foothills of Mount Aso volcano, Fluval Bio-Stratum substrates contain a powerful blend of nutrients and minerals to support healthy plant growth and stable water conditions.
Infused with dormant beneficial bacteria, Fluval Bio-Stratum activates when exposed to water. These bacteria help break down waste and initiate the nitrogen cycle, rapidly reducing ammonia levels and stabilizing water chemistry in new aquariums.
Designed for planted and aquascaped tanks, the substrate is porous, non-compacting, and lightweight with a 1-3mm powder granule structure. This allows fine and delicate plant roots to easily penetrate and spread.

I’ve used the 2kg size in my 50-liter planted tank. The roots spread well and my plants grew stronger within a month. The water clarity improved noticeably after a few weeks. Easy to mix and no compaction issues.

The substrate works well with my Java fern and Anubias. It’s lightweight and doesn’t settle or compact. I noticed a drop in ammonia levels after the first week. A bit pricey, but worth it for planted tanks.

I mixed it with sand for a natural look. The plants rooted easily and the water stayed stable. The bacteria helped reduce ammonia quickly. Great for beginners in planted aquariums.

Used the 1kg for a small tank. It’s easy to handle and the granules are fine enough for delicate plants. No issues with root penetration. Slight delay in visible plant growth, but overall very satisfied.
