🔥Description🔥
The Resun SP-2500L is a professional-grade internal aquarium filter built for strong circulation and efficient multi-stage filtration. Powered by an 18W motor and delivering up to 1400 L/H, this compact unit is ideal for medium-to-large freshwater tanks (recommended up to 400 L) where strong turnover and reliable biological filtration are required.
The SP-2500L features two detachable canisters preloaded with green sponges and black bio-balls to combine mechanical particle removal with excellent biological surface area for beneficial bacteria. Designed for continuous underwater use, it carries an IPX8 rating for submersible operation. The unit mounts internally using 4 suction cups and has a slim, space-saving footprint (15 × 36 × 7 cm). Maintenance is simple — remove canisters, rinse sponges in tank water to preserve bacteria, replace media as needed, and reattach.
