Installation was a snap. I have provided a bunch of photos of the box, pump, disassembled parts and size references. That's a US quarter for size reference.
When the pump starts, there's a possibility of rattle from the impeller blade because it can slide the length of the metal shaft it turns on, but it did not cavitate the way my Seios do on startup.

The thing I like alot about these over Seio's is that you can keep them closer to the surface since the more open design doesn't tend to create intake vorticies that cause "sucking" sound and micro bubbles.
I think I'm going to get another. 2x850 is wicked turbulent for a 25g, but they'll rule when my 60 cube goes up.

Hello. If you go here you will read some problems that I had with that product and also you can read the answer of the technician of the Hydor. A friend of mine has the same problem with me.
Can you please tell me if your pump works normally or not?

As far as I can tell, the pump works as designed. Flow comes out the front in a pattern similar to my Seio, though it seems only slightly more intense than my 620 gph Seio, so it may not be as forceful.
The impeller does shoot out and clatter briefly on startup. I don't use a wave maker so this is not an issue for me. However, I have never found a power head that uses the standard magnet-driven impeller that doesn't clatter on startup from the magnetic field ramping up and rattling the impeller magnet.
I didn't take note of the impeller's magnetic power specifically. The magnets are probably fairly weak on the impeller to improve inertia which would allow lower power. Power heads designed for greater lifting power and water pumps like Mags have stronger magnets to get more push.

Just a heads up, Fosters & Smith have the Koralia powerheads on sale. Of course I didn't post this till after I placed my order. They seem to sell out fast. Koralia Powerheads
Drs F & S is one of the best run businesses we reefers have and I highly recommend them. NO, I have no connection with them other than being a former WI resident and an on going customer.
Here's my latest purchase (just completed). I wanted 2 Koralia pumps, one 3 and one 4. The 4 was out of stock. I instant messaged with a rep and was told to order both and they would send the out of stock pump when it comes in at no further shipping cost.
That's service. Thank you Drs F & S!

Dick I wholeheartedly agree with you. Dr. F&S has the best return policy I have ever seen. I ordered 2 bulbs from them for a fixture I had. Turns out the bulbs weren't the problem the ballast was bad. They told me to just return the bulbs and they would refund my money. My LFS has a strict no return policy on bulbs.
Wow I knew the Koralia would sell out quick. I placed my order yesterday. I almost waited till today. Of course I picked up 2 more buckets of Reef Crystals and only paid $15.99 shipping. Fed Ex guy is going to hate me... again.
is it just me or what, the fosters seem too cheezy for my liking! they post reasonable info, its just they are proclaimed experts on every subjuct which makes me think twice.

The Foster's are veterinarians and take a serious approach to their business. Being from WI, their home base and my former home, I've been in their operation several times and must say, I'm impressed. They go out of their way to hire good, well informed people and then put them through a continuous training program. Not at all like your LFS. These people are well paid in comparison to LFS wages. They run their warehouse and phone center 24/7, the last I heard. In my humble opinion, they are one of, if not, the best on line operation for the pet industry.

I buy a lot of my dry goods from them and have exchanged and returned things. They have always been great. I bought Reef Crystals on sale for $31. My LFS sells that bucket for $70. I do wish they had a better selection on some items.
I bought my live rock at liveaquaria and it was as good as advertised. Even with the shipping i bought 70 pounds of rock for $328 and the shipped weight was 80 pounds. I sure can't buy live rock locally for that price. The one piece of live rock i bought locally has glass anemones on it.
Got my Koralia 4 today. Love the flow. Now I just need to order 2 more to replace the Seio 1500. I like the looks of the Koralia's, not as bulky as the Seios. May have to replace the Seio 620's in the nano. The lower wattage is nice also.
