To keep your fish healthy, you want to have an aquarium air pump. Air pumps produce air bubbles that maintain a proper concentration of oxygen. The bubbles also add a lively, friendly ambiance for your fish and you, too. Air pumps also allow you to use a sponge filter if that’s your preference. Sponge filters tend to be inexpensive, a definite bonus, and support the growth of beneficial bacteria for thriving aquariums. Here are some aquarium air pumps we recommend for you.

Shopping for an Air Pump

Here’s what you’ll want to look into:

  • Flow rate: Airflow rate matters a lot! And how you decide on the optimal rate for your tank depends on several factors. You need to take into consideration the size of your aquarium and the type of fish you have. By doing some simple research, you’ll find an answer.
  • Noise Level: If you’re buying an aquarium air pump, you probably already have an aquarium, so you know where it’s located or perhaps where you want to move it. Noise matters. If your tank is sitting in your or your child’s bedroom, you want a quiet air pump. Honestly, most quality air pumps are quiet, but it’s worth looking at the details.
  • Tank Size: Large aquariums need a powerful air pump. The converse is true for small tanks. Again, the goal is to maintain an adequate concentration of oxygen for the health of your fish.

Not all aquarium air pumps are submersible, but this one is, and it’s high-tech. The pump’s motor—oh wait, there is no motor! It operates via a thin piezoelectric ceramic plate that assists in reducing noise.

Creating less than 35 decibels of sound, the hygger mini shouldn’t interrupt sleep or mental focus. It’s a great little air pump for 1-to-15-gallon tanks placed in a bedroom, desk, or kitchen.
