Aquarium pumps help to add more flow to your aquarium, sump or pond. An air or submersible pump will create a lot of circulation around either of these. Circulation in the aquarium is vital to help regulate temperature and move along any stagnant areas of water. Will also help in moving debris around for your filter to suck up and remove, thus keeping your tank cleaner and healthier. Some fish live in fast flowing river systems, others live in a more placid environment. Choose a pump that will suit the needs of your particular aquarium. Whether you need more air movement or water flow, these aquarium pumps below will help you to achieve that.
