Powerful yet extremely quiet, the Fluval Q1 Air Pump produces consistent air flow thanks to an advanced swing-arm and diaphragm design. A thick double-wall outer casing, integrated pump well and noise-suppressing baffle chamber make Fluval one of the quietest air pumps to date.
The Q1 is quality constructed and will provide lasting and reliable performance for aquariums up to 300 L (80 U.S. gal).

AIR FLOW ADJUSTMENT
The Fluval Q2 air pump incorporates a flow control knob (rheostat) to control air output. Turning the knob clockwise increases the air flow and counter-clockwise reduces the air flow. Proper air flow control reduces harmful back pressure and lengthens the service life of the pump. Q.5 and Q1 air pumps are not equipped with flow control; in which case an air control valve can be used to regulate air output (sold separately).
In order to achieve correct airflow, a balance between the valve setting and the pump output is necessary. The ideal setting is obtained by minimum back pressure or non restriction of flow of air. Never physically restrict the output of the pump. Restriction causes damage to the diaphragm (see BACK PRESSURE section for more information). Adjust air valve output as required. To regulate air volume using an air control valve with multiple outlets, it is recommended to have the last valve available to release excess air pressure build up (see BACK PRESSURE section for more information). In regulating the air pressure, it is best to work from the valve farthest from the input of the air valve. Remember to have the last valve completely closed so as not to lose any air pressure. Proceed to make adjustments on the remaining valves. Once the adjustments are complete, slowly open the last valve to the point where no loss of air output is noticed from the items controlled by the other valves. To achieve and maintain an equal balance of air pressure to the accessories in the aquarium, further adjustments of the air valve may be required depending on the items powered by the air pump.
Note: If the first valve on the air control assembly is fully opened, air volume to the remaining outlets will
To alleviate excess air pressure or overproduction of air, it is recommended to open the last valve every 2 weeks or when required. In doing this, you will increase the life of the pump and diaphragms by preventing premature wear.
Back pressure is the build-up of pressure on the diaphragm due to restricted air flow. This occurs when excess air is produced by the air pump, or when the air channels are inadvertently blocked. Back pressure over time resulting from clogged air stones or other air system blockages and restrictions will cause the diaphragm to expand or rupture. An expanded diaphragm leads to a loss of air volume while a rupture results in the total loss of air.
AIR STONE, AIRLINE, AND ORNAMENT MAINTENANCE
This pump requires no regular internal maintenance during its life. The rest of the air system should be periodically checked and cleaned.
• Airlines should be carefully inspected whenever standard aquarium maintenance is performed. Adjust, or if required, replace all sections which are pinched, kinked, or otherwise damaged.
• All attached air-driven aquarium ornaments should be regularly maintained. Algae growths should be removed from moving parts and kept as clean as possible. Internal air tubes should be cleaned.
• Air stones should be kept clean and free of debris or algae build-up. The ideal situation is to replace them every month, alternating with an extra set which has been dried over that period and cleaned before being placed in the aquarium.
Two complete sets of air stones alternately changed each month will extend the life of the air stones and help keep back pressure to a minimum. Clogged air stones and air-driven aquarium ornaments will lead to low air pressure output and also reduce the life of the diaphragms.
TROUBLE SHOOTING TIPS
If the air pump fails to produce air, check the following:
1. Ensure that the air pump is plugged in.
2. Ensure that there are no blockages in the air hose assembly and that all valves allow air passage. If no air is produced by the accessories in the aquarium, remove the air line from the pump and ensure that air is being produced.
3. If the air pump produces no output, the most common problem encountered with any air pump is a ripped or weakened diaphragm. Remove airline. Unplug appliance. Inspect the diaphragm for tears or rips. Any opening in the diaphragm will make it impossible for the pump to produce air for aeration purposes. Always inspect the diaphragm first before replacing other parts in the pump.
