HITOP 4W Aquarium Air Pump Review: Airflow, Noise and Betta Use

As an Amazon Associate we earn from qualifying purchases. Details

If you are considering the HITOP aquarium air pump, the first questions are how much air it moves and whether your tank needs that much. An air pump supplies air and moves water at the surface, and a betta tank may need far less than a community tank. This review covers only what the listing states about airflow, pressure, noise, power, valves, tubing, warranty and included parts. It does not report any test of the pump in a tank, and it does not claim the pump will keep a fish alive or oxygenate a tank. Use the listing to decide whether the pump fits your tank, and check the fish’s needs before you add any equipment.

Quick answer

The HITOP is a black, shark-shaped air pump with two outlets, a 120-volt corded power source and a 4-watt rating. The specs list an airflow of 7 liters per minute and a maximum pressure of 22 kilopascals, and the title gives 110 GPH. The bullets describe an adjustment knob for airflow and a power button, and they say the pump is quieter than 35 decibels. The kit includes two 5-foot air tubes, two air stones, two check valves, two suction cups, a T-connector and filter cotton. The specs give a 2-year warranty.

What to check in an air pump

Four details decide whether this pump fits. Each one can rule it in or out.

1. Airflow and rating. The specs give 7 liters per minute, and the title gives 110 GPH. These are different units for airflow, so check which figure you need on the product page before you compare with another pump. The title says it suits tanks from 20 to 200 gallons, which is a wide range, so the airflow you need depends on your tank and equipment, not on the tank size alone.

2. Power and rating conflict. The specs list the wattage as 4 watts and the horsepower field as 6 watts, and the bullets call the motor 4W. The field labelled horsepower is a watt figure, so read the power as 4 watts. The power source is corded electric at 120 volts, so keep the cord clear of water.

3. Noise claim. The bullets say the pump runs quieter than 35 decibels because of a two-layer design with a vibration-absorbing shell. The listing gives that figure without a test condition, so treat it as the maker’s maximum rather than a measured level in your room.

4. Tubing, valves and warranty. The specs list 10 feet of hose, but the included components and the bullets describe 5-foot air tubes, so check the length on the product page. The kit includes two check valves and two regulating valves, and the specs give a 2-year warranty.

Use these rules to choose:

• Choose this pump if you want a corded two-outlet pump with an adjustable knob and a warranty, and you have confirmed the airflow you need.
• Choose a different pump if you need a tube length of 10 feet, because the included tubes are described as 5 feet.
• Choose a different pump if you need a measured noise figure, because the listing gives the decibel claim without a test condition.

The HITOP air pump

The pump is a plastic, black unit with a shark design, an automatic operation mode, and a power button. The specs give the item weight as 1.2 pounds and the product dimensions as 6.3 by 4 by 4.3 inches. The model number is 806, and the manufacturer is listed as Haisen. The department field reads “Aldult”, which is a typo on the listing. The included components are the tubes, air stones, check valves, regulating valves, suction cups, a T-connector and air filtering cotton.

The pump fits a reader who wants an air pump for a tank that will run air stones or a sponge filter, and who wants to adjust the output with a knob. The bullets say the pump has a power button, so you do not need to unplug it to stop it.

The listing has several things to check. The horsepower field lists 6 watts while the wattage field lists 4 watts, as noted above. The hose length in the specs is 10 feet, while the included tubes are 5 feet each. The title says 20 to 200 gallons, and the listing gives no airflow requirement for that range. The department field has a typo.

Who should skip it: a reader who needs a measured noise figure, a reader who needs 10-foot tubing, and a reader who needs a clear airflow figure in one unit before buying.

Air and a betta tank

The Wikipedia overview of the Siamese fighting fish says bettas are exceptionally tolerant of low oxygen levels and poor water quality, because a labyrinth organ lets them take in surface air. That means a betta does not need an air pump to survive, and a strong airflow is not a betta requirement. Choose airflow to suit the gentleness the fish needs, and set the knob low if you do run a pump with a betta.

The bullets say the knob adjusts the output and the kit includes air stones and tubing. The listing does not describe which filter or setup the pump runs, so check that the setup you choose is gentle enough for the fish you keep.

Worked example: how a 15-minute test sits inside a 2-year warranty

Compare that time with the 2-year warranty in the specs, so you can see how little of the warranty the test uses.

• Warranty term: 2 years, from the specs.
• Setup check in this example: 15 minutes.
• Warranty remaining after the check: the check uses under one percent of the term. Check the listing for the exact terms.

Check the arithmetic again. 15 minutes is a small fraction of two years. The example shows that a setup check is short next to the warranty term. The listing does not describe a warranty claim process, so keep the receipt and check the product page for the terms.

What an air pump does in a tank

The Wikipedia overview of air pumps says a pump used to aerate an aquarium supplies air through an airstone. It works because a moving part, such as a vane, piston or diaphragm, creates a low-pressure area that draws in more air. The listing describes two outlets and included air tubes and air stones.

Why oxygen matters to the filter

The UF/IFAS guide to ammonia says nitrifying bacteria need oxygen and alkalinity to convert ammonia and nitrite. If oxygen levels are not sufficient, the bacteria can stop working or die, and ammonia and nitrite levels rise. The guide was written for aquaculture systems, but the same bacteria work in a home biofilter. The guide does not discuss air pumps, so check dissolved oxygen with a test rather than assuming the pump supplies enough.

Five common mistakes

1. Comparing airflow units. The specs give liters per minute, and the title gives GPH.
2. Reading 6 watts as horsepower. The horsepower field lists 6 watts, and the wattage field lists 4 watts.
3. Trusting the noise figure as measured. The 35-decibel claim has no test condition.
4. Assuming 10-foot tubing. The included tubes are described as 5 feet.
5. Running the pump with a betta at full output. Bettas tolerate low oxygen, so set the knob low.

FAQ

How much airflow does it give?

The specs give 7 liters per minute. The title gives 110 GPH.

What power does it use?

The specs give 120 volts, 4 watts and corded electric power.

Is it quiet?

The bullets say quieter than 35 decibels. The listing gives no test condition.

Can I adjust the output?

Yes. The bullets describe a built-in adjustment knob.

What is the warranty?

The specs give 2 years.

What comes in the box?

Two air tubes, two air stones, two check valves, two regulating valves, two suction cups, a T-connector, filter cotton and a manual.

Bottom line

The HITOP air pump suits a reader who wants a corded two-outlet pump with an adjustable knob, a power button and a 2-year warranty for air stones. The listing gives 7 liters per minute and 110 GPH, a 4-watt rating, and a 35-decibel noise claim without a test condition. The horsepower field reads 6 watts, and the tube length conflicts between fields. Confirm the airflow you need, check the tube length, and set the knob low for a betta.
