Even though fishes do not have lungs, they get their oxygen from the water by their own way to live in. They use their ‘lungs’ to get oxygen from the air, so the oxygen in the water that fishes absorb is called dissolved oxygen.
As we all know, air has 21 percent oxygen while oxygen in water is a rare resource. However, fish only need a tiny amount of dissolved oxygen, they are able to live well if the dissolved oxygen is at least five parts per million. Otherwise, fish will eventually suffocate and die. So, if you get no real water plant in your fish aquarium, air pump is in need.
Maybe you will think if fishes really need an air pump as they just need tiny dissolved oxygen. In fact, if you are going to keep more fishes in your tank and especially, winter is coming soon, air pump is necessary for the fish aquarium. There are many advantages to get an air pump. Firstly, you can confirm your fish always get enough dissolved oxygen to live; secondly, air pump can be used to run internal box filter and sponge filter; thirdly, air pump is also a decoration of fish tank. But to find a good air pump to fish tank is not that easy, because there are too many different kinds of air pumps in the market nowadays. Please allow me to recommend the new kind of air pump to you: submersible air pump.
Submersible air pump gets the new idea to either be placed on the bottom of the tank or the side glass of the tank. With strong rubber suction cups, submersible air pump reduces noise and vibration itself. In addition, it has the air flow control adjuster which can produce more air to supply sufficient oxygen. Moreover, with high quality LED lamps, it can perform soft blue light for beautiful view. Also, the completely water-proof design which make submersible air pump safer and more reliable.
To own a submersible air pump make your fish tank be more fashion, more than that, you also can keep your fish healthy and happy.
