⚙️ How to Use

Hang the filter on the tank rim so the intake and skimmer section sits at water surface level.

Prior to powering up, fill the filter chamber with aquarium water to prevent dry‑running.

Plug in the unit and adjust the flow knob to suit your aquarium’s inhabitants (gentle flow for fry/shrimp, moderate for community fish).

For best skimming results, ensure the water surface is flat and free from heavy movement to maximise skimmer performance.

Maintain the sponge and media regularly: rinse mechanical sponge in tank water during water changes, replace carbon cartridge as needed (typically every 4‑6 weeks).

Check the surface skimmer intake periodically to remove any collected debris or floating waste.

🐠 Why Choose This Filter?

If you’re looking for a space‑efficient, multi‑stage filtration solution that also tackles surface film and floating debris, the WP‑618H is a smart choice. The included surface skimmer feature is particularly valuable in planted tanks, shrimp tanks and setups where clear surface water and optimal gas exchange are important. The slim form factor keeps the tank clean and uncluttered, while the 3‑in‑1 media setup offers reliable water clarity and biological support.
