KW DoPhin CF388 mini CANISTER FILTER

• Compact and silent operation: Designed to hang neatly on the aquarium with low vibration and quiet performance.
• Surface skimmer: Includes a 360° vortex surface skimmer to remove oil, dirt, and film from the water's surface.
• Multi-stage filtration: Uses a filter medium with a sponge and a renewable charcoal block, with a portable filter chamber that is easy to access and clean.
• Adjustable flow rate: The flow can be adjusted to suit the specific needs of your aquarium.
• Easy maintenance: Features a "hang-on" accessory and a quick and easy disconnect system for straightforward cleaning.
• Water circulation: A rain bar output helps enhance oxygenation and create water movement. 

• Recommended for: Tetras, guppies, mollies, platies, swordtails, bettas, dwarf cichlids, shrimp, and snails.
• Not suitable for: Large or "messy" fish like goldfish or arowana, unless used as a supplementary filter. 

• Leaks: Leaks can be caused by a broken valve block, improper installation of hoses, or a dried-out or faulty O-ring.
  • Solution: Ensure the O-rings are properly lubricated and positioned. If the problem persists, the seal or valve block may need replacement.
• Noisy operation: A rattling sound from the filter is often caused by a broken or dislodged impeller.
  • Solution: Unplug the filter, check the impeller for damage, and reseat it properly.
• Stopped working or making bubbles: This is often due to an air lock caused by air bubbles getting stuck in the intake tube.
  • Solution: Unplug the filter and re-prime it by filling it with water. You can also slowly tilt the filter on its side to shift the air bubble.
