    Great affordable powerhead for smaller tanks. Super compact design without comprising efficiency and adjustable flow direction.

    Koralia Nano 425 – best suits a marine tank from 15-30 gallons.


    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.
