Betta Nano Filter: Precision Internal Filtration for Nano and Shrimp Aquariums

The Betta Nano Filter (model nano-filter) presents a streamlined engineering solution for micro-aquascapes. Its core is a 2-watt submersible AC pump operating at 220-240V/50Hz, designed for continuous duty with minimal energy draw and negligible acoustic output (rated 'Very Low' noise level). The pump's fixed 150 LPH flow rate is meticulously chosen to provide adequate turnover for tanks up to 25 liters, preventing stagnation without creating excessive current that could stress nano fish or shrimp. This flow is critical for effective nutrient transport to the filter media and for maintaining oxygenation. Filtration is executed through a singular, yet highly efficient, stage. The proprietary fine sponge media serves a dual function: * **Mechanical Filtration**: Its dense pore structure physically traps suspended detritus, uneaten food, and particulate matter, ensuring water clarity. The material type (foam) allows for a high surface area to volume ratio, crucial for trapping fine particles without rapidly clogging. * **Biological Filtration**: The intricate matrix of the fine sponge provides an expansive anaerobic and aerobic surface for beneficial nitrifying bacteria (Nitrosomonas and Nitrobacter) to colonize. This bacterial colony is vital for the biological cycle, converting toxic ammonia (NH3) into nitrites (NO2) and then into less harmful nitrates (NO3), maintaining a stable biochemical environment. The absence of chemical filtration is a design choice that simplifies maintenance and avoids potential complications with sensitive inhabitants or planted setups. The filter's compact dimensions (70x40x100mm) ensure minimal tank intrusion, while the plastic construction guarantees corrosion resistance in freshwater. Its 'auto-restart' feature is a crucial safety and convenience engineering detail, ensuring the filter resumes operation automatically post-power outage, preventing prolonged lapses in filtration. The direct impeller drive from the submersible pump to the single media chamber minimizes hydraulic losses, contributing to the efficient 150 LPH performance relative to its 2W power consumption.
