Does this have the mechanical stopper to prevent from starting in reverse? If not, which AC powerhead does
Question by: Nick on Apr 19, 2016 6:21:00 PM
Great question!
The Hydor will have the ribber mechanical stop which prevents them from rubbing in reverse. Feel free to let us know if you have any further questions!

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.

  • Support Killed It For Me By Happyjackson on 3/5/2016

    The pump arrived missing a bushing, didn't work at all. It was 7 days before I could get any support from the manufacturer. I finally got tired of it and bought another brand locally. When the manufacturer did responded there was more time wasted with photos and shipping the part. 13 days after I received the original pump I got my part. A part that didn't fix a thing. Upon closer examination there is a small chunk of the potted plastic that's used to seal the motor in the hole where the bushing goes, the bushing won't go in the hole. I can't pick the plastic out. The moral to this story. Nobody really stepped up to make this right, but I got a better pump locally for twice the money, ouch. $32 for a little pump, I guess it was a bargain, right?
  • Limited By Cover By Joe on 2/21/2016

    Works fairly well in my 13 gallon. The flow seems pretty concentrated, not spread out. I cut a few pieces off the front cover and it works much better. Solid product, and great customer service from Hydor if anything breaks.

  • Great little pump By Chefbill on 12/22/2015

    These little pumps work great. I use it in a small frag tank.
  • Koralia Nano 240 running for a year now By Eric on 9/18/2015

    I bought two of these for my 48 gallon bow front tank. I have one on each side aimed towards the bow of the tank. I am quite impressed on how much flow is produced. In the future I am going to get a wave maker module and try them out with that.
  • Good powerhead for a very small tank By SurlyT on 6/4/2015

    Nice little pump if you don't need to push water very far or hard. In a 10-20 gallon tank they're probably just right. But I have 2 of them in a 28g cube (21" on a side) and the flow doesn't get all the way across. I either need 1-2 more of the 240s or an upgrade to the next model up.

    Haven't owned them for very long so I can't speak to their longterm reliability, but I've had good experiences with Koralia PHs in the past.
  • Compact By Guahan Reefer on 4/11/2015

    I own three of these. 2 in a 15 gallon Nano and 1 in my first chamber of a 20 gallon refugium. Suction cup magnets so you do not have to worry about it detaching from glass/acrylic. Great water flow for its size.
  • Small, Compact, and Effective By Guapoveli on 3/25/2015

    They get the job done plain and simple. They don't take up a lot of space.
  • Good for the price By jesus on 1/22/2015

    First I'd like to say for the pump does its job for being so inexpensive, how ever i highly doubt they provide anywhere near the claimed GPH. But they do well in tanks that are not that long or deep since they cant push water far at all. I had a 425 in a 4 gallon pico tank and it was much weaker than I thought it would be but perfect for the tank anyways since at 425 GPH it would have been over 100x turnover. If you are in the market for a koralia 565 I'd save a few more pennies and buy a jebao RW4 instead.
  • great choice By Christopher on 12/24/2014

    I run two of these in my 29g softie tank. The flow it gives to the Xenia is wonderful.
  • Small, silent with powerful magnetic suction cup mounts. By shawn on 7/1/2014

    Has wide flow and pushes alot of water for it's size. At 3.5 watts It's perfect as my battery backup pump. Mounted high and pointed up to break the surface. Should run for 6-7 hrs in a power outage.
  • Nano 425 By Monica on 4/25/2014

    This is a nice little pump. I have one in my IM mini 30g. I need more circulation than just one pump. It's great little pump just need one more on the other side.
