HITOP Dual Outlet Aquarium Air Pump

The HITOP dual outlet air pump is a 3W aerator for fish tanks from 10 to 100 gallon. It has two outlets, manual air adjustment and a thick ABS body with soft rubber foot pads to dampen noise. HITOP includes a 1 year warranty.

Manual adjustment

HITOP chose manual air control over electronic regulation. The brand argues that this avoids shakes and electric field fluctuation and has a lower failure rate. In practice, a simple valve is easy to set and does not drift.

Replaceable intake cotton

Air pumps draw room air through a small filter. Dust and pet hair clog it over time, which cuts output and wears the diaphragm. This pump has a replaceable air intake cotton, and one spare comes in the box.

Full kit contents

• Return valve x2 (check valves)
• Air stone x2
• Air tube, two lengths of 4.9ft
• Suction cup x2
• Air regulating valve x2
• T-connector x1
• Spare air intake cotton x1

The extra regulating valves let you fine-tune each line on its own, which is handy when one outlet runs a sponge filter and the other an air stone.

Placement

Set the pump above the water line on a soft pad. Run each line through a check valve, arrow toward the tank, then through a regulating valve if you want separate control.

Good uses

This is a fit for community tanks, goldfish tanks and breeding setups running two sponge filters, like the hygger double sponge filter. Change the intake cotton every few months in dusty rooms.

Compare

For a quieter, lower-power pick on smaller tanks, see the Pawfly 50 GPH pump.

When output falls, check the intake cotton first, then the stones, then the tubing for kinks. Most weak-air problems come from one of those three, not from the motor itself. A pump with a clean intake can run for years with no other care.
