Boyu Protein Skimmer WG-308

The Boyu Protein Skimmer WG-308 is a nano-scale internal protein skimmer designed to remove dissolved organic compounds and particulates from saltwater and reef aquaria. Compact yet effective, WG-308 improves water quality by creating dense micro-bubbles that capture organics before they break down, thereby reducing load on biological filtration and helping maintain stable water chemistry. Because it is small and quiet, the WG-308 suits nano tanks, reef setups, or sumpless systems where space is limited.

Why choose WG-308?

Firstly, it delivers reliable skimming performance while using very low power, so it is energy-efficient and cost-effective. Secondly, the unit is easy to assemble and disassemble, which simplifies cleaning and routine maintenance. Finally, its slim profile allows flexible placement inside sumps, filter compartments, or inside the tank itself.

Features & benefits

• Efficient removal of dissolved organic matter to improve clarity and reduce algae pressure.

• Low power consumption (around 6 W) for economical operation.

• Compact dimensions ideal for nano and small marine aquariums.

• User-friendly design — quick to assemble, easy to clean and maintain.

• Can be used in freshwater (for protein/particulate removal) and marine systems, but it’s optimized for saltwater performance.

Typical specifications

• Power consumption: ~6 W.

• Recommended aquarium size: roughly 60–120 L (suitable for many nano tanks).

• Flow rate / pump: ~120 L/h (varies slightly by retailer/spec sheet).

• Dimensions (approx): 117 × 85 × 260 mm (check your retail box for exact measurements).

• Voltage: AC 115/230 V, 50/60 Hz depending on region.

Installation & maintenance tips

• Install where steady water flow will draw bubbles through the skimmer body for best foam production.

• First, rinse the skimmer parts with aquarium water to remove dust; then fit the pump and test foam output.

• Clean the collection cup and neck weekly or as needed to maintain performance. However, avoid over-cleaning the pump housing so beneficial microbubbles remain consistent.

• If noise increases, check for trapped debris or adjust placement to reduce vibration against hard surfaces.

Safety & handling
Always unplug before servicing. Do not run dry or pump water above 40°C. Keep out of reach of children and inspect electrical cords regularly for damage
