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.

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.

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.

Smaller than I anticipated, but just as much power as I had hoped for.

Quite and just the right amount of flow in my Nuvo 16. Corals and fish love the extra flow.

Very small size great for nano tanks. Easily controlable. Takes care of flow in the hard to reach places to keep deutritis to a minimum.

I have 2 of these in my Nuvo 24. I purchased to supplement my Nuvo 24. Produces just the right amount of current to allow awesome coral growth. Small enough so that they blend in well. I don't like to see a lot of hardware in my display.

This pump works great, is super quiet, and gives just enough flow to move the water in our 10 gallon tank.

great powerheads By Cory on 4/5/2013

I have two of these on a Koralia Smartwave controller in my IM Mini 38 tank. They are great and I love the magnet mounts. I have a number of Koralia powerheads scattered around the house on various tanks and they have all been great. In this case Nano powerheads are perfect for the smaller tanks and are just the right amount of flow to create the current you need to keep debris pockets from forming while at the same time not turning a smaller tank into a whirlpool. I also have the smaller Nano on my IM Nano 8 tank and appreciate the small footprint seeing that I have limited space.
