The Boyu WF-2035 is the most compact and energy-efficient hang-on-back filter in the Boyu WF series, designed specifically for nano aquariums, small planted tanks, and aquascapes. This ultra-quiet waterfall-style filter delivers effective 3-layer filtration in a slimline design that fits snugly on smaller aquarium edges without compromising water quality.

Key Benefits:

  • Ideal Flow Rate (300L/h): Delivers 2-3 complete water turnovers per hour for tanks 20-40 liters—perfect for nano setups, shrimp-only tanks, and delicate planted aquariums
  • 3-Layer Filtration System: Combines mechanical, chemical, and biochemical filtration to remove debris, odors, and impurities while establishing beneficial bacteria colonies
  • Ultra-Low Power (4.6W): Extremely energy-efficient—one of the lowest-wattage HOB filters available; ideal for 24/7 operation without noticeable impact on electricity bills
  • Whisper-Quiet Operation: Superior shock absorption and vibration dampening ensure near-silent performance—perfect for bedrooms and office aquariums
  • Compact Slim Design: Dimensions 184 x 98 x 301mm—the smallest in the WF series, ideal for tight spaces and nano tank setups
  • Waterfall Aeration: Specially designed cascade flow naturally increases oxygen and promotes CO₂ diffusion—excellent for planted nano tanks and sensitive species
  • Surface Oil Film Processor: Automatically removes surface biofilm and contaminants for crystal-clear water
  • Adjustable Flow Control: Fine-tune water circulation with easy-to-use regulator knob—slower for delicate fry or carpeting plants, faster for standard planted tanks
  • Easy Assembly & Maintenance: Simple plug-and-play installation with built-in pump and filter media; no additional equipment needed
  • Suitable for All Aquarium Types: Works in freshwater, planted, shrimp, and community nano setups

Perfect For: Nano aquariums (20-40L), small planted tanks, betta tanks with plants, shrimp breeding tanks, desktop aquariums, office aquariums, and aquascapers prioritizing silent, space-saving filtration.

How to Use / Instructions

Installation & Setup:

  • Verify power supply: AC 230V/115V, 50/60Hz, 4.6W
  • Mount on side or back of nano/small aquarium edge
  • Important: Keep inlet tube vertical and positioned as close to water surface as possible for optimal intake
  • Critical: Maintain water level above the filter motor at all times to ensure proper auto-priming. If water level falls below motor, the filter will stop when power is cut and may fail to restart automatically
  • Fill filter chamber with water completely before powering on
  • Plug into power outlet and adjust flow rate with control knob at bottom
  • Do not run the filter dry under any circumstances

Operation:

  • Maximum flow rate: 300 L/h (5 LPM)
  • Recommended tank size: 20-40 liters (5-10 gallons); suitable up to 60 liters with weekly water changes
  • Filtering area: 17 sq. cm
  • Dimensions: 184mm (L) x 98mm (W) x 301mm (H)
  • Operating power: 4.6W
  • Frequency: 50/60Hz

Filter Media Maintenance:

  • Check mechanical filter (foam/floss) every 1-2 weeks for debris accumulation
  • Rinse mechanical media gently in tank water only (never tap water—kills beneficial bacteria)
  • Replace or rinse chemical media (activated carbon) monthly or as needed
  • Biochemical media only requires cleaning if flow rate noticeably decreases
  • Clean intake tube every 2-3 weeks to prevent clogging in nano tanks
  • Note: Filtering area is compact (17 sq. cm)—maintain regular cleaning schedule

Water Chemistry:

  • Waterfall design naturally increases oxygen levels—excellent for high-oxygen-demand species
  • Ideal CO₂ diffusion for low-tech planted nano tanks
  • Gentle flow suitable for sensitive shrimp species and delicate plants
  • Reduces nitrate accumulation in smaller water volumes with weekly 30-50% water changes

Tank Compatibility:

  • Best performance with frequent water changes (30% weekly for heavily planted tanks)
  • Ideal for shrimp-only tanks (gentle flow won't disturb substrate or plants)
  • Perfect for nano planted aquascapes (30-40L volume)
  • Excellent for betta tanks with live plants (low flow prevents stress)

Troubleshooting:

  • Filter stops after power outage: Ensure water level is above motor; manually refill if needed
  • Reduced flow: Clean intake tube first, then mechanical filter media
  • Filter wobbles: Secure mounting brackets firmly to tank edge
  • Motor hums but no flow: Prime filter by completely filling chamber with water
  • Air bubbles in outlet: Normal during first run; should clear within 30 seconds

Important Safety Notes:

  • Never touch the electrical plug with wet hands
  • Keep power cord clear of water and away from handling areas
  • Unplug before any maintenance or cleaning
  • Not suitable for outdoor ponds or large tanks
  • Use GFCI outlet recommended
  • Do not immerse electrical components in water
  • Keep out of reach of children

Recommended Maintenance Schedule:

  • Weekly: Inspect intake tube; perform 30-50% water change
  • Bi-weekly: Rinse mechanical filter media in tank water
  • Monthly: Replace activated carbon; check biochemical media flow
  • Quarterly: Deep clean all accessible filter components
