Don't go with an off the wall brand name.Powerheads can help deter the growth of algae, as some types grow better in calmer, less turbulent water.The water movement and current provided by powerheads are a source of exercise for fish.Position them appropriately in your tank. Many corals and anemones do not do well in high current areas, while others thrive on good strong current. Water moving over the animals helps to carry oxygen to them, brings food to stationary animals, and stimulates animal activity. They aid in the health of the tank inhabitants.Powerhead circulation permits the majority of these particulates to be circulated or suspended, allowing them to be filtered out by a mechanical filter. They help to keep detritus and other tank matter from settling on the bottom of the tank.The more your tank water is circulated and filtered, the better the water quality is in the aquarium.Powerheads provide important water circulation and oxygenation in the aquarium, far more efficiently than the bubbles from air stones do.
