Excellent powerheads. Well made with good materials. This is not some cheap brittle 3rd world plastic junk. I would advise against use with a wave timer as they tend to start a little hard. I don't know if it is bad for the pump but I don't like the sound it makes so I set that pump to run constant. I use this in a 55 gallon mixed saltwater tank, it is overkill for a 55 but it moves some serious water. I think 100gal and larger tanks would be better. I cannot comment on the durability of the #3 pump because it is still new, however, the Koralia nano pump I have has been in use 24/7 since I bought it and it is almost 3 years old. The nano is covered in coralline algae and is still working smooth. I would not aim the #3 at branching frogspawn or hammer corals or similar unless they are at the other end of the tank. They seem to push a little violently on delicate corals. Mine sits about 2-3 feet away everything but zoa polyps and they don't seem to mind the wicked current. Amazon had them listed for $20.00 dollars cheaper than any of the local stores around here. Nice simple way to move 850+/- gallons an hour. I would buy another.

I have a freshwater 72 gal Bowfront aquarium. The pump adds only a very low hum to the room and is easy to place with the magnetic bottom. My one criticism is that the pump cant swivel 90 degrees on its base. The maximum the pump can swivel is probably 45 degrees. I would have liked to attach it to the back of the tank and swiveled it to point it to the back corner. Instead its attached to the side and pointed straight to the opposite back corner. The pump works so well that I probably could have used the Koralia 2 in my 72 gal tank. The plants in the opposite corner from the pump are leaning and the one large angel fish took a little time to get used to the force of the current. The shape of the angel fish works like a sail if it in the wrong position. After the initial snow globe effect, the quality of the tank water is much improved and all the fish are doing good.

Positives: 1) Moves a lot more water than think it will;
2) The magnetic connector is rock solid, works better than epoxy on coral frag- you will be impressed.
3) Compared to some of the competitors (Tunze, Vortech, etc) it is reasonably priced
4) Works just as well as the next generation models ( I have both)
5) As a result of have such a strong connection to the tank wall, the aim can be safely adjusted with removing the unit
6) Easy to clean, few moving parts- and the replacement parts are cheap
7) I've never met a dead spot this pump can't fix.

Negatives: 1) Move a lot more water than you think, the have different sizes for a reason. Water movement is not like filtration- Bigger isn't always better;
2) Not designed to be turned off and on with regularly. It'll run forever if left alone (and I mean years), but will burn out out if you put it on a timer with anything less than a 10-12 hour interval;
3) This series cannot be synced, to generate a true wave pattern;
4) Takes up a lot of tank real estate and can be difficult to hide;
5) Some of algae eaters are taken off guard by the way the pump pulls in water. It pulls water from the sides, not the back.
I watched an Otoclinus move from the tank wall to the pump, w/o realizing the current direction... we call him lefty now.

I don't want to leave a negative impression; This is a great pump and with the newer model out you can get these for a good price. If you look closely you'll see a lot of them at LFS's

Just buy the right size for you livestock

(fyi- The Koralia 1 is under appreciated. Even in a bigger tank it can provide just the right amount of added water movement to a tank running power filters.)

This was a great product and just as described. I received this item right own , time and it was used just as they described..

I initially purchased this power head for my 55 gallon tank with the a plan to add another to help my zoanthids stalks shorten and grow together. When I received the item it was actually the Koralia 1050 (the new and improved Koralia 3) and it works great. The flow in my tank could not be any better and the zoanthids love it. Not only did they give the upgraded pump, it came to my doorstep incredibly quickly.

I ordered two powerheads, one came with a missing part and I called the company and they sent out another one right away and arranged for shipping to return the one with the missing part. excellent service....

i have 2 of them. one for each side of my 55g saltwater tank and they are working very well

The pumps only lasted 4 month, can not get them to start back up. I took them to a fish store next to my house and they told me they need cleaning, so they cleaned them for me. The pumps still can start up.I e-mailed the shipper waiting for them to contact me.
