Tank Preparation and Partition Modification

The initial step involved cleaning the Fluval Flex tank and preparing the partition. Existing elements were removed, ensuring a clean slate for the modification. A pre-existing partition was repurposed and glued to another piece for added support. This enhanced its stability and overall aesthetic within the tank.

Additional work was done to address a missing portion of the partition. A piece of plastic was sourced, intended to seamlessly fill the gap and maintain the tank's visual appeal. The goal is to create a visually clean and tidy partition that suits the needs of the Betta fish.

Substrate and Filter Placement

The substrate preparation involved using Fluval stratum, Tetra complete substrate, and additional materials to enhance the tank's bottom layer. The speaker deliberately chose not to wash the stratum, relying on the tank's filtration system to handle the process. The aim is to blend various substrate types for optimal visual and functional results within the aquarium.

The Fluval U2 filter was strategically placed at the rear of the tank. Its directional jets are employed to provide effective water flow without disturbing the partition or the fish. This strategic positioning promotes a natural and healthy environment.

Tank Filling and Final Setup

The tank was gradually filled with water, allowing the substrate to settle naturally. Additional elements, such as the heater and filter, were carefully integrated into the system. A unique trick of placing a sponge on the end of the heater hose was mentioned to avoid dust entering the pump.

The final touches involved adding decorations such as a coconut shell and ensuring the filter was properly installed. The tank was kept at a temperature of 25 degrees Celsius, a suitable environment for betta fish. The setup also accounts for adequate swimming space and hiding places.

Filter Media and Conclusion

The video showcased the Fluval U2 filter's modular design, allowing for easy media changes. The creator opted for phosphate-removing filter pads instead of carbon, prioritizing water quality suitable for both the fish and any snails present. This approach aims for long-term tank health.

Overall, the Fluval Flex divider mod proved to be a successful and visually appealing setup for Betta fish. The incorporation of various substrates, the strategic placement of the filter, and careful attention to water parameters resulted in a thriving aquarium environment. The modular design of the Fluval U2 filter adds to its versatility and ease of maintenance.
