Tips from our Techs These pumps are ideal for creating a bubble wall in tall aquariums. They're strong enough to easily push air into deep aquariums, helping release toxic gasses and allowing oxygen to enter.
Installing your Whisper Air Pump
Use a check-valve between the pump and the aquarium if the Whisper Air Pump is placed on a surface lower than the water level of the aquarium. The check valve helps stop water from siphoning into your air pump in the event of an electrical power failure or when removing filters from aquariums. To avoid damage for accidentally spilled water, do not place the pump directly below the aquarium.
Place the Whisper Air Pump on a shelf at least 12" higher than the water level of the aquarium, but not directly above the aquarium. NOTE: The shelf should have a raised edge to prevent the pump from sliding off.
Use a Whisper Air Pump with two ports for alternate installation. NOTE: Use a Tee connector with your two-port Air Pump for applications that require only one source of air.
Air-control valves create multiple air sources. Use the valves to route the air from the Whisper Air Pump to different tanks, filters, airstones or air-operated ornaments.
Adjust the air-control valves to regulate air supplied to tanks, filters, airstones and air-controlled ornaments. On three-way valves, Knob 1 regulates airflow to Nozzle 3, and air flows through Outlet 2 unimpeded. Use end caps at the end of the line.
Maintaining your Whisper Air Pump
Clogged airstones usually cause airflow loss. They become blocked as algae, floating debris, and mineral deposits accumulate in the pores over time. If you notice a diminished airflow, blow through the airstone yourself. If this is difficult, replace the airstone.
Worn diaphragms or other rubber parts can also diminish airflow.
Clean the outside of the pump with a damp cloth and mild detergent.
Don't take the quality of your tap water for granted. If you draw your water from a well, nature may not be providing you the perfect balance. If you are using tap water from your municipal department, it likely includes minerals and additives.
Algae are prolific and opportunistic organisms that take advantage of aquarium systems that are out of balance. Water quality issues create ideal conditions for algae. This article explains how proper water quality helps control algae.
Bubbles beautify your aquarium display, improve water quality, and make your aquarium more hospitable for inhabitants. With an air pump, airline tubing, an air check valve, and a touch of creativity, you can easily create a cascade of bubbles.
Please note: Return of electrical equipment to Drs. Foster & Smith for exchange or refund is limited to 60 days from the date of purchase. Beyond 60 days, please contact the manufacturer for repair or replacement as covered by the manufacturer's warranty.
