User Ratings and Reviews
5 Stars Excellent water movement
Compact and versatile. Low wattage so does not raise tank temperature. Optional magnet holder (included) eliminates noise against glass tank. Magnets are coated with thin plastic, so no rusting as previous generation product. There are newer models with different GPH and improved pivoting spec. Check your options before you order.
5 Stars I really like this pump
I have it in my 21 gallons nano tank and it’s producing a lot of current. It’s totaly silent and the holding mecanism is fantastic. I just wish there would be a bit more range in adjusting the pump direction because. It is well built. I have read that some people cut off the bars in front of the impeller to create more flow but for my 21 gallons it’s more than enough so no modification for me.
4 Stars Great powerhead, but there are some concerns about the magnet
I love how this powerhead stays put. It doesn’t slide, and will stay aimed in whatever direction you point it. It does tend to accumulate debris and floating macroalgae, so you should make sure that it gets cleaned often.
There was some concern about the magnet that’s used, and how it’s prone to rusting. Not sure how this affects water chemistry, but here’s a link for those who are interested:

I’ve been using this powerhead for about 5 months now, and have seen the rusting on the magnet, but can’t really tell if it is doing anything to the water.
4 Stars Nanote
I have a 10g nano reef tank that I have been enjoying for about a year now. I recently added the Koralia Nano to the tank. The amount of flow this little head produces is impressive. It took my corals 2 or 3 days to adjust to the movement because it was such a drastic change in water flow. Now my fish are more lively (they love the current) and my corals are more vibrant. I really like the dynamic it adds to the tank.
The machine itself appears well built and extremely simple. It has a suction cup and magnet that hold the head stationary inside the tank and another suction cup and magnet that goes on the outside of the tank for added adhesion. You plug it in and it circulates water: one speed, no switches, no adjustments.
3 Stars Broke after 1 year
I have 2 of these in my 20-long reef tank. One broke after about a year, the other one is still going. It’s a great product for all the reasons other reviewers have stated. But a 1-year lifespan is pathetic. 5 stars for functionality, 1 star for quality.
