Description
The SunSun HW‑5000 Frequency Filter is a high-capacity, multi-stage filtration system built to maintain clean, clear, and healthy aquarium water. It sits outside the aquarium (usually in a cabinet below) and circulates water through several filtration media layers, removing waste, toxins, and impurities.
A key highlight is its variable frequency (DC) pump, which allows users to adjust the pump speed and flow rate electronically rather than running at a fixed speed. This makes it quieter, more energy-efficient, and adaptable to different tank sizes and fish requirements.
