## Features

- 4-IN-1 MULTI-FUNCTION FILTRATION SYSTEM - Combines filtration, oxygenation, water circulation, and wave making in a single compact unit. Effectively removes waste, boosts oxygen levels, and keeps aquarium water clean, fresh, and crystal clear.
- IDEAL FOR MEDIUM-SIZED TANKS (1.5–2.5 FT) - Powerful 15W motor delivers a high 880 L/hr flow rate, perfect for tanks between 1.5 to 2.5 feet. Not suitable for very small or large tanks, as strong flow may stress delicate fish.
- WHISPER-QUIET PERFORMANCE & LOW MAINTENANCE - Runs silently without disturbing your surroundings — perfect for home or office aquariums. For best results, clean the sponge every 15 days, replace 30–50% of the water, and avoid overfeeding or excessive lighting to maintain clear, healthy water.
- EASY TROUBLESHOOTING IF NOT WORKING - No water flow or air bubbles? Simply check for a blocked impeller, clogged pipe, or improperly submerged outlet. A quick clean or adjustment usually restores full function within minutes.
- NOT SUITABLE FOR DELICATE OR SMALL FISH - Avoid using with sensitive species like Betta, Guppies, Tetras, Angelfish, Arowana, or Discus. Best suited for hardy, active fish that thrive in strong water currents.
