Full Details

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.

  • Hydor Evolution 1500 pumps By RJH on 9/20/2014

    You eventually (in weeks) get a algae bloom and have to run them on a wave maker. I was successful with 1500's, many of them, dual bottom/back,left and right, on outlets 3 and 4, and another two on outlets 1 and 2 on a Wave Master Pro from Red Sea. Calm, or sleep mode in turbulent mode are slow enough so the clicks on start up are not constant. This also seems to clean pumps which will otherwise grow and spread nuisance algae.
  • This "1650 Magnum D/C pump" or a 1500 evolution on wavemaker By JFK on 9/4/2014

    In order to create colliding linear flow you need a wave maker and enough flow to keep on nutrients in flight until they are removed by a skimmer or mechanical filtration. The 1500 evolution was supposed to solve the problems with the 1400, they still click, This pump one failed to start on a wave maker and would just make a different noise than the click of a 1500 for ten seconds, The other the black color and rubber disappeared and a piece of rubber is probably in my bubble blaster pump for my reef octopus skimmer. Initially compared to a power head because it is a circulation pump you are impressed, than it becomes low quality throw away pumps like Maxi jet, but these run terrible on wave makers required for the "perfect" environment for corals or just coralline algae for the bright colors.
  • Great Product By electricblue on 7/16/2013

    Moves alot of water; for my reef fish display tank

    I picked it to add alittle more water movement

    only down side it is a bit bulk

  • Whoa...thats a lotta flow By Joe on 3/23/2013

    I didn't realize how much water it really moved til I had to take the Sargassum out of my refugium and put it in the DT. I'm impressed.
  • pump By bejo on 3/8/2013

    Nice pump very powerful.
  • KORALIA MAGNUM 2,250gph By onlylight36 on 5/21/2012

    all i can say is WOW this pump push's a ton of water in my tank. It sure keeps my tank sturred up. I love this in my reef/fish system.
  • Bulky but good By Jeffrey on 4/6/2012

    This is a good "little" power head. Quite and moves a lot of water. The only negative is it is rather bulky and a little unsightly in the tank. But not as unsightly as a algae outbreak.
  • great pump By Dustin on 2/7/2012

    i love the koralia pumps,i have 2 of them and I plan on replacing all my others with them.they are quiet,powerfull and my favorit part is the stay on the glass unlike other power heads that fall off all the time blasting my sand all over
  • lots of flow By donald on 10/31/2011

    I have 180 gallon sps tank and bought this to increase my flow inside my tank.i must say that i was impressed how much water this thing move andit is a great price.
  • wow By austin on 10/6/2011

    i purchased this and an evo 1400 to start out with for my 180. this thing really pumps out some flow. def double the 1400. I wanted a stronger powerhead for my "weak side" return, and i think this one will do the job. it will move sand six feet away if angled properly. the only downside is that this thing is huge. but compared to other models, the price evens it out.
  • great pump for the cash By Ethan on 12/23/2010

    Great pump it is a little big about the size of a large orange or a softball maybe. All the magnum pumps are the same size so if you are looking into them id make sure you have a 100 gallon or bigger so the size of the pump won't overwhelm your viewing panel. I have mine on the back wall with rock around it which helps alot. Other than that it is a awesome pump good flow and no start up issues so far.
