Fluval Stratum is an active substrate specifically designed to create ideal aquatic environments, primarily by naturally softening water and reducing carbonate hardness (KH) without staining or discoloring the aquarium water. It is highly beneficial for planted aquariums, shrimp tanks, and for fish species that thrive in soft, acidic water conditions.
Key Functions and Benefits of Fluval Stratum
Fluval Stratum serves multiple crucial roles in an aquarium ecosystem, contributing to water quality, plant health, and overall stability.
1. Water Parameter Management
One of the most significant features of Fluval Stratum is its ability to modify water chemistry to suit specific aquatic life.
- Softens Water: The granules actively work to reduce the general hardness of the water, making it suitable for delicate plants and soft-water fish species.
- Reduces Carbonate Hardness (KH): It naturally lowers the carbonate hardness, which helps buffer the pH towards a slightly acidic range. This is particularly advantageous for many popular aquarium plants, most shrimp species, and certain tropical fish that originate from soft, acidic environments. Regular KH testing is recommended to monitor water parameters effectively.
- Maintains Clarity: Unlike some natural substrates, Fluval Stratum is formulated to perform its water-softening functions without staining or discoloring the aquarium water, ensuring a clear and aesthetically pleasing view.
2. Promoting Plant Growth
Fluval Stratum is an excellent choice for planted aquariums due to its unique composition and structure.
- Nutrient-Rich: Made from volcanic soil, it contains essential nutrients that are gradually released, providing a stable and long-term food source for plant roots. This helps promote strong growth and vibrant coloration.
- Optimal Root Development: Its porous, non-compacting structure allows for excellent water circulation around plant roots, promoting healthy growth and preventing anaerobic pockets which can harm roots. The soft texture also makes it easy for plants to root firmly.
3. Supporting Aquarium Ecosystems
Beyond water parameters and plant health, Fluval Stratum also fosters a healthier overall aquarium environment.
- Beneficial Bacteria Colonization: The highly porous surface area of the granules provides an ideal habitat for the colonization of beneficial nitrifying bacteria. These bacteria are essential for the nitrogen cycle, effectively converting harmful ammonia and nitrites into less toxic nitrates, leading to clearer water and a healthier environment for fish and invertebrates.
- Ideal for Shrimp: Its water-softening and pH-buffering properties make it an excellent substrate for shrimp species, such as Neocaridina and Caridina, which often prefer softer, slightly acidic water conditions for optimal health and breeding.

| Non-Discoloring | Maintains clear aquarium water | Aesthetic appeal, easy monitoring |
Tips for Using Fluval Stratum
To maximize the benefits of Fluval Stratum, consider the following:
- Rinsing: While generally clean, a light rinse before use can help remove any fine dust particles. Avoid excessive rinsing, which can deplete some of its initial beneficial properties.
- Planting: Its lightweight and soft nature make planting easy. New plants can be gently inserted directly into the substrate.
- Water Changes: Perform regular, small water changes to maintain overall water quality and introduce fresh trace elements.
- Water Parameter Monitoring: As Fluval Stratum actively alters water chemistry, regular testing of pH, KH, and GH is recommended to ensure parameters remain within the desired range for your specific aquatic inhabitants.
Fluval Stratum is a highly effective substrate for aquarists aiming to create a thriving planted tank or a specialized habitat for sensitive species requiring specific water parameters.
