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.

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.

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.

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.

Quite and just the right amount of flow in my Nuvo 16. Corals and fish love the extra flow.
Great for nano tank By Loren on 9/15/2013

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.
Just right for my Nuvo 24 By Barbra on 9/7/2013

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.
