Hydor Koralia 12V Controllable Powerhead

High flow is very important to maintaining a thriving healthy aquarium. Aquariums with poor flow can experience a number of easily avoidable health issues. Using high flow powerheads in your aquarium will:




• Significantly decrease the risk of algae outbreaks.
• Keep waste and particles suspended longer so skimmers and filters have a better chance of removing them.
• Prevent toxic pockets from forming in hard to reach areas.
• Keep debris from collecting on corals.
• Keep food suspended longer so you can add less food.
• Increase the chances of long term healthy tank success.
