4. Setup Instructions

Unpack Components: Carefully remove all components from the packaging. Verify that all parts listed in Section 3 are present and undamaged.
Assemble Pump: Attach the inlet strainer to the bottom of the impeller cover. Ensure the impeller is correctly seated within the pump body, then secure the impeller cover. Connect the air tubing to the air intake nozzle on the pump body and attach the adjustable air regulator to the other end of the air tubing.
Position Pump: Submerge the pump completely in your aquarium. Use the suction cups on the pump locator to firmly attach the pump to the inside wall of the aquarium. Ensure the pump is positioned where it can create optimal water circulation and aeration.
Adjust Air Regulator: Position the adjustable air regulator above the water surface. This allows it to draw in air for aeration.
Connect to Power: Once the pump is fully submerged and securely positioned, connect the power plug to a suitable electrical outlet.

5. Operating Instructions

The AquaMiracle Powerhead Pump is designed for continuous operation to maintain water circulation and aeration in your aquarium.

Water Circulation: The pump creates a steady underwater current, which is beneficial for active fish species and helps to move fish excrement and debris towards the aquarium filter, contributing to a cleaner and healthier environment.
Aeration: The included air tubing and adjustable air venturi allow the pump to draw air from above the water surface and release it as fine bubbles into the aquarium, supplementing oxygen supply. Adjust the air regulator to control the amount of air introduced.
Heat Distribution: By circulating water, the powerhead helps to distribute heat evenly throughout the tank, preventing "cold spots" and ensuring that aquarium heaters operate efficiently to maintain a consistent temperature.
