## Long description

Advantages
The AquaClear Powerhead 20 combines low energy consumption with steady flow performance appropriate for small aquaria. Its compact design enables discreet placement inside the tank or on the aquarium glass without occupying significant space. The pump contributes to even temperature distribution, enhances the efficiency of mechanical and biological filters, and helps maintain water quality through continuous circulation. Construction and materials are suitable for both freshwater and saltwater environments when installed and maintained according to manufacturer guidance.

 Small freshwater aquariums requiring improved surface agitation and circulation

Key specifications
 Power consumption: 4.5 W
 Type: Aquarium circulation pump / powerhead
 Intended use: Continuous water circulation and surface agitation
 Application: Suitable for freshwater and saltwater tanks
 Mounting: Compact design for in-tank or glass-mounted placement
How to use
Install the AquaClear Powerhead 20 following the mounting method recommended for your aquarium glass or internal placement, ensuring the pump is fully submerged if required by the model design. Position the outlet to direct flow along the tank length or toward filtration intake to minimise dead spots. Connect to a suitable mains supply and verify steady operation. Regularly inspect the impeller and intake for debris and clean according to maintenance guidelines to preserve flow performance and prolong service life.
Usage recommendations
 For optimal results, combine the Powerhead 20 with existing filtration by directing flow toward the filter intake and avoid pointing the outlet directly at delicate livestock. Perform periodic maintenance: disconnect power before cleaning, remove the impeller for inspection, and rinse components in dechlorinated water. Adjust placement and flow direction to balance circulation with the behaviour and needs of plants and animals in the aquarium.
