Designed for the prefiltration of larger dirt particles sera biofibres are perfect for biomechanical prefiltration, efficiently trapping larger dirt particles. This way, you can safeguard the subsequent filter media from heavy contamination and enhance the biological performance of your filter. They are compatible with freshwater, saltwater, and pond water filtration systems. Additionally, sera biofibres serve as a fantastic spawning medium and provide a safe hiding spot for fry. They are also ideal for transporting shrimps – the fibres offer a stable grip for the creatures in transport bags, reducing their stress levels during transit.

12,000 Kelvin - A brilliantly intense blue light - Mimics the lighting conditions found in tropical rivers and lakes. Thanks to its well-balanced spectrum, sera Blue sky can serve as a standalone tube or be paired with sera Deep sea, making it an excellent light source for marine aquariums. The pairing with SERA Tropic Sun is ideal for freshwater aquariums. Proper aquarium lighting is essential not just for fish — it's also crucial for any live plants thriving in your tank. Plants rely on light for photosynthesis to create food from carbon dioxide and water. For instance, tropical plants typically require 12 hours of light daily, while plants from cooler waters need light that adjusts with the seasons. IMPORTANT: The lifespan of aquarium lamps is 12 months. The lamp's spectrum gradually alters, and after this duration, it is no longer effective as an aquarium lamp for its intended purpose. To achieve optimal results, be sure to replace aquarium lights every 12 months. In essence, watts indicate the energy consumption of a light, lumens measure its brightness, and Kelvins define the color of the light.

12,000 Kelvin - A strikingly bright blue light - Mimics the lighting conditions found in tropical rivers and lakes. Thanks to its well-balanced spectrum, sera Blue sky can be utilized as a standalone tube or alongside sera Deep sea, serving as an ideal lighting option for marine aquariums. When paired with SERA Tropic Sun, it provides the best lighting conditions for freshwater aquariums. Effective aquarium lighting is crucial not only for fish but also for any live plants thriving in your aquarium. Plants require light for photosynthesis to create food from carbon dioxide and water. For instance, tropical plants typically need around 12 hours of light daily, while plants from cooler waters require varying light durations throughout the seasons. IMPORTANT: The lifespan of aquarium lamps is 12 months. Over time, the lamp's spectrum shifts, and after this duration, it can no longer serve its intended purpose as an aquarium lamp. To ensure optimal performance, it is recommended to replace aquarium lights every 12 months. In essence, watts indicate the energy consumption of a light, lumens measure brightness, and Kelvins define the color of the light.
