Aquarium Air Pumps & Aeration for Freshwater Fish Tanks
Aquarium air pumps are one of the quiet workhorses of a healthy freshwater aquarium. They help increase oxygen, improve water movement, power sponge filters, and create the bubbles that keep fish, shrimp, and beneficial bacteria thriving.
At Tropical Treasures Wyo in Cheyenne, Wyoming, we carry quiet, reliable air pumps and aeration supplies for freshwater aquariums of every size, from nano shrimp tanks and betta setups to community aquariums, breeding tanks, and large display tanks.
Air Pumps, Air Stones & Aeration Supplies
Shop trusted aquarium air pump brands like AQUATOP Breza, Tetra Whisper, Hygger, Aquarium Co-Op, and Lees, along with the accessories needed to complete your setup. We carry air stones, airline tubing, check valves, splitters, control valves, suction cups, and sponge filters.
We also carry battery-backup air pumps, which are a great emergency item to keep on hand during power outages. A backup air pump can help keep water moving and oxygen available when your main equipment is down.
Which Air Pump Is Right for Your Aquarium?
The best air pump depends on your tank size, how many sponge filters or air stones you want to run, and how much airflow you need. A single sponge filter in a 10–20 gallon aquarium usually only needs a small, quiet air pump. Larger aquariums, multiple sponge filters, or several air stones may need a stronger pump or a dual-outlet model. In our lineup, the AQUATOP Breza AP-20 suits tanks up to 20 gallons, the AP-30 covers tanks up to 40 gallons, and the AP-40 handles tanks up to 50 gallons.

Aquarium Air Pumps FAQ
What does an aquarium air pump do?
An aquarium air pump pushes air through airline tubing to power air stones, sponge filters, bubble walls, and other aeration accessories. This helps improve oxygen exchange and water movement.
Do all aquariums need an air pump?
Not every aquarium needs one, but air pumps are very useful for sponge filters, shrimp tanks, fry tanks, quarantine tanks, and aquariums that need extra surface movement or backup aeration.
Are sponge filters powered by air pumps?
Yes. Most sponge filters need an air pump, airline tubing, and sometimes a check valve to operate properly.
Do I need a check valve?
Yes, a check valve is strongly recommended if the air pump sits below the aquarium waterline. It helps prevent water from siphoning back into the pump during a power outage.
What size air pump do I need?
Choose an air pump based on tank size, depth, and how many sponge filters or air stones you plan to run. Larger aquariums or multiple accessories may need a stronger pump or dual-outlet model.
Are air pumps good for power outages?
Battery-backup air pumps are excellent emergency equipment because they help keep oxygen moving when the power goes out.
