Aquael FZN PRO 700 Hang On Cascade Filter for Aquarium 75-130L

Aquael FZN PRO 700 Hang On Cascade Filter for Aquarium 75-130L – Quiet, Customisable Cascading Filtration

The FZN PRO 700 is a high‑performance, hang‑on cascade filter engineered to deliver gentle yet effective water movement for a wide range of aquarium sizes. With a 700 l/h flow rate and an energy‑efficient 6.2 W motor, it maintains a tranquil environment—just 32 dB, quieter than most filters.

Its modular media chamber lets you choose between pre‑loaded cartridges or bulk materials, ensuring the filtration style suits your specific tank needs, whether you prefer mechanical, chemical, or biological cleanup. The waterproof motor eliminates the need for priming, and a telescopic intake tube offers precise adjustment to match substrate height.

How to Use This Cascade Filter

1. Position the filter at the tank edge, ensuring the intake tube starts above the substrate.
2. Adjust the telescopic intake tube to match your tank height, securing it with the rubber seal.
3. Set the desired outflow level using the circular regulator, placing the spout flush with the water surface for a smooth cascade.
4. Turn on the switch; the underwater motor kicks in instantly, beginning filtration without the need to prime.
5. Use the speed‑knob to fine‑tune the mechanical strength; higher settings provide more particulate removal.
6. When needed, bind the cartridge cover and remove the cartridge or bulk media for cleaning or replacing.
7. For a crystal‑clear surface, attach the optional skimmer to the intake tube; adjust its top section to sit above water during feeding.

Care & Maintenance Tips

• Clean the cartridge or bulk media every 4–6 weeks depending on tank load.
• Rinse the filter chamber and intake tube with aquarium water during maintenance to avoid contamination.
• Inspect the speed‑control knob and intake/outflow regulator for smooth operation.
• When dumping bulk media, place the filter chamber upside down to avoid water splashing into the housing.
• Check the skimmer (if installed) for debris buildup often; a clean surface enhances aeration.
• Do not expose the filter to temperatures outside the manufacturer’s 12–32 °C operating range.
