Fire protection classes B1 and F90 are classifications used to determine the fire resistance of building materials. B1 indicates a material with a high level of fire resistance, able to withstand flames and prevent the spread of fire for a certain period of time. F90, on the other hand, signifies a material with an even higher level of fire resistance, capable of withstanding fire for a longer duration. These classifications are important for ensuring the safety of buildings and occupants in the event of a fire. **

The Fluval Fresh F90 features a 3-stage filtration system that ensures optimal water quality for your aquarium. The first stage is mechanical filtration, where a foam pad traps debris and particles from the water. The second stage is chemical filtration, using activated carbon to remove impurities, odors, and discoloration. The final stage is biological filtration, where beneficial bacteria colonize on the biomax media to break down harmful ammonia and nitrite into less harmful nitrates. This comprehensive filtration system helps maintain a healthy and balanced aquatic environment for your fish and plants. **

Then, apply the fire-rated sealant around the cable where it passes through the wall to create a fire-resistant barrier. Make sure to follow the manufacturer's instructions for the sealant application to ensure proper sealing and compliance with fire safety regulations. **
