Hydor is pleased to announce their new Koralia Third Generation line of powerheads. The Koralia Third Generation is super compact, energy efficient and is ideal to recreate the natural and beneficial water motion of rivers and seas. With a lower profile than previous models, and new DMSS (Dual Magnet Support System) system getting flow where you need it has never been easier. Hydor has put new motors inside their third generation pumps which leads to more flow for every watt. The new Koralia pumps can also be hooked up to a wavemaker or controller and set to intervals of seconds to hours.


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.



  • Flow Rate: 1350 GPH
  • Max Glass Thickness: 0.6 Inches
  • Power Consumption: 5.5 watts
  • Cord Length: 6 feet


Two sizes of fish guards, flow diffuser, and cable protector are included.

Product Questions

i have a 75g, 4 foot long tank. what is the recommendation for 2 powerheads? For example two 1350gph?
Question by: Raymond on May 31, 2017, 12:43 AM
There is a wide range of flow and recommended turnover rates depending on your desired setup and whether you are going high energy/sps dominated or low energy softy, or somewhere inbetween, and aquascaping can also play a role. Typically you can shoot for a turnover rate of between 20 and 40 times per hour of the display volume, and this can be achieved through any number of powerheads, though we would recommend at least 2.

Happy reefing!

Would one of these be to much flow for my 33 gallon aquamax cube?
Question by: Shane on May 25, 2017, 11:48 AM
I wouldn't necessarily say this is too much flow for your tank, but this will depend upon your tank setup and whether or not this is intended to be a high-energy sps type of tank, or a softie/mixed reef. If you are looking for a high energy system, then this would be fine. If not, then I would likely select something with a little less power.

Happy reefing!

How many of these for a 125 6 foot long tank? Or should I go with a larger power head. If so, which size and how many?
Question by: Anthony on Nov 7, 2016, 7:48 PM
Great question! I would actually recommend two or three of the Tunze 6105 series for that size of a tank. The max GPH on those are 3400GPH. :-)
