About This

• 3-IN-1 FILTRATION, CIRCULATION & GENTLE CURRENT - This submersible internal aquarium filter combines filtration, water circulation, and soft wave-making in one unit. Even flow helps reduce dead spots so debris moves to the intake—great for freshwater community, betta, and shrimp tanks that need clear water without a harsh current.
• SPACE-SAVING CORNER DESIGN FOR MORE SWIMMING ROOM - The triangular body tucks into a back corner so plants and décor stay in view. AQ237-3W (3W, 79 GPH) fits about 2–10 Gal; AQ237-6W (6W, 132 GPH) fits about 10–40 Gal. Freshwater use only—not for saltwater aquariums.
• DUAL-STAGE SPONGE + FLOSS FOR CLEARER WATER - Black high-density sponge traps fish waste, leftover food, and debris; white floss catches finer particles and helps reduce odor for crystal-clear freshwater. replace the sponge cartridge about every 7 days.
• ADJUSTABLE FLOW WITH STYLISH SPRAY BAR - Turn the top regulator for gentle spray (bettas, guppies, fry) or a stronger sheet for planted tanks. The horizontal spray bar spreads return flow to promote surface agitation and help break surface film—no separate noisy air tube needed.
• SNAP-OPEN CLEANING - Unplug, pull off the filter cup, and snap it open from the middle—no tools. Includes spray bar, cartridge(s), 6 suction cups, and manual. Shake underwater to release air before first use; keep water above the MINIMUM WATER LEVEL mark.
• Powerful Filter with Whisper Operation – Designed with low-noise technology for whisper-quiet performance, this submersible fish tank filter maintains a peaceful environment in bedrooms, offices, or living rooms without disturbing you or your fish.
