⚙️ How to Use

Hang the filter unit on the edge of your tank, making sure the intake/skimmer section sits at the water surface level for optimal skimming.

Before switching on, fill the filter chamber with aquarium water to avoid air locks.

Power it on, and adjust the flow output to suit your aquarium setup (gentler for shrimp or delicate plants, stronger for community tanks).

Regularly maintain the system: rinse the mechanical sponge during water changes, replace chemical media as needed, and keep an eye on surface skimmer intake to ensure it’s not clogged with film or debris.

Ensure the skimmer intake is unobstructed to maintain efficient removal of surface film and floating particles.

🐠 Why Choose the WP‑628H?

If you’re after a neat, efficient filtration solution that also handles surface cleaning without needing a separate skimmer, the SOBO WP‑628H is an excellent choice. The built‑in surface skimmer adds value by keeping the water surface clear of oils and films, which is especially beneficial for planted tanks, shrimp setups, or aquariums where gas exchange and light penetration matter. Its slim form factor ensures it won’t clutter your setup while still providing solid performance.
