The importance of water movement in aquariums is often overlooked.
Essential to the nourishment of all aquariums, water currents also regulate
water qualities, resulting in a more enjoyable environment for your
In a properly circulated aquarium, heat is evenly distributed for uniform
water temperature, unwanted debris is unearthed and removed by mechanical
filtration systems, and gas exchanges at the water's surface efficiently
releases carbon dioxide and increases oxygen. Currents also contribute to
fish health by offering slight resistance while swimming.
The easiest way to increase or create water currents within your aquarium
is by investing in a powerhead. By doing so, you will be ensuring constant,
consistent water flow that will eliminate any "dead spots", providing
oxygen and maintaining consistent temperatures.
