SOBO WP-Series Top Filter

Over-the-tank (top-mounted) aquarium filter for small to medium tanks

🐠 What It Is

• The WP-Series Top Filter is a top-mounted filter that sits on the rim of the aquarium.

• Combines a submersible pump with a filter tray to provide mechanical, biological, and optional chemical filtration.

• Water is drawn from the tank, passes through filter media in the tray, and returns clean, circulated water.

• Keeps the interior of the tank uncluttered, leaving more space for fish, plants, and décor.

⚙️ Features

• Mechanical filtration: Sponge or floss pads remove debris and waste.

• Biological filtration: Space for bio-media like ceramic rings to support beneficial bacteria.

• Chemical filtration (optional): Can add activated carbon or other chemical media.

• Good water circulation and oxygenation via pump and return flow.

• Top-mounted design allows easy access for media maintenance without disturbing the tank.

• Models available for small to medium tanks, with flow rates suited to the tank size.

✅ Benefits

• Saves interior tank space; keeps the tank neat.

• Provides comprehensive filtration (mechanical + biological + optional chemical) in one unit.

• Improves water circulation and oxygenation, reducing dead zones.

• Easy to maintain; media is accessible from the top.

• Customizable filtration media according to tank needs.

• Suitable for community tanks, planted tanks, and general freshwater setups.

⚠️ Limitations

• Not ideal for very large or heavily stocked aquariums; may require additional filtration.

• Flow may be too strong for delicate fish, shrimp, or fry if not adjusted.

• Requires regular maintenance; clogged media can reduce flow.

• The pump must stay submerged; pump failure or clogging stops filtration.

• Must fit tank rim; compatibility with tank hood/lid should be checked.

🎯 Best Use Cases

• Small-to-medium aquariums needing full-featured filtration without internal clutter.

• Community tanks, planted tanks, or general freshwater setups.

• Situations where easy maintenance and customizable media are desirable.

• Tanks where you want to maximize swimming space for fish and plants.

🧰 Setup & Maintenance Tips

• Mount firmly on the tank rim; keep pump intake submerged.

• Load media thoughtfully: coarse sponge first (mechanical), then bio-media, optionally carbon or fine floss.

• Rinse or replace media every 2–4 weeks, depending on tank load.

• Monitor flow; check pump for clogs if flow drops.

• For delicate species, adjust flow to avoid stressing fish or disturbing plants.

• For heavily stocked or large tanks, consider combining WP filter with additional filtration.
