🌊 RS Electrical Waterfall Style Bio-Filter (RS Electrical RS Series)
Multi-Stage Filtration • Waterfall Return for Strong Oxygenation • Adjustable Flow • Four Models for Tanks up to 300L
 
📋 The RS Electrical Waterfall Style Bio-Filter is a hang-on-back filter that gives your aquarium full multi-stage filtration. Mechanical media catches waste and debris, chemical media such as activated carbon removes toxins and odours, and biological media gives beneficial bacteria a home to keep the water clean and healthy.
Filtered water spills back into the tank over a wide waterfall spillway, agitating the surface for excellent gas exchange and carrying oxygen-rich water down to the lower levels of the tank. A knob on top lets you set the flow to suit your tank and fish.
Maintenance is quick: lift the lid, rinse or replace the media, and any uneaten food or waste is easy to spot and remove before it breaks down. Four models cover nano tanks right through to 300L setups, from the 2.5W RS 1000 to the 1600 L/H RS 4000.
