              How To Choose The Best Aquarium Air Pump For Multiple Tanks?

              Types

              When choosing an aquarium air pump, you need to first decide which type of pump to use.

              • Battery-powered air pump: these are wireless, compact, and portable units designed for those who want a small pump. They work as well as they’re supposed to. However, they have limited working time and you will have to change the battery when they run out of power.
              • Plug-in air pump: this type can work continuously as long as it’s plugged into an outlet. It doesn’t have an on/off switch so you just need to plug it in and the machine will start working.
              • Dual operation: this is a hybrid version combining the two former types. It can either be plugged into an outlet or run on a battery. The best thing is that the backup battery will kick in as soon as the electricity is out. The downside of this type is its hefty price.

              Flow Rate

              The flow rate, measured in gallons per hour (GPH), indicates how much air an air pump can generate at a certain speed.

              When considering this factor, you need to take your tank capacity into account. For instance, a 40-gallon tank will need a 240GPH flow rate.

              The choice of flow rate should also depend on the type of fish and plants you put in the tank. For a baby or smaller fish, you should apply a low flow rate, and vice versa.

              Noise Level

              A loud pump can be very irritating, so you should choose a device with the lowest noise level possible.

              Remember to check the noise level (dB) on each product, any level between 30 and 44 dB is considered quiet. You shouldn’t compromise for higher levels.

              FAQs

              How big of an air pump do I need aquariums?

              This is related to the flow rate of the pump and depends on the size of your tank as well as your fish, a smaller tank will need a small pump only. Besides, small, baby fish are also suitable for a small pump.

              Can you have too many air bubbles in a fish tank?

              If you are using the right aquarium equipment, you won’t likely have too many bubbles in the tank. However, keep in mind that too much oxygen can be stressful for the fish.

              How do I filter multiple aquariums?

              This is how you can build one filter for two tanks.

              • You need to make a U-shaped PVC pipe that connects the tanks.
              • Make an overhead filter using a plastic planner, PVC adapter, a small PVC pipe, sponges, and the media.
              • Use a long, curved pipe to connect the overhead filter with the pump so that the pump is at the bottom of a tank.
              • Put the overhead filter on top of the tanks and connect everything else.

              You can see the detailed guideline in this video:

              How does the air pump work?

              An aquarium air pump works by agitating the surface water to increase the surface area of the water, which allows oxygen to get into the water through gas exchange. Gas exchange happens on the surface of the tank water when there’s excess CO2 released into the air and O2 taken in.

              When an air pump produces bubbles, it raises the surface area and the tank will release more CO2 while taking in more O2.

              How to install an air pump?

              You need to follow these steps:

              1. Connect the pump with the air tubing
              2. Install the check valves, Y-valves, or T-valves
              3. Connect the air stones with the tubing
              4. Plug the pump in an electrical outlet

              Conclusion

              This is the end of our comprehensive guide on choosing the best aquarium air pump for multiple tanks, hopefully, the post will make it much easier for you to find the right air pump for your tanks. Good luck!
