Not impressed
| Installation and Operation |
Overall I'm not to happy with this product. The nozzle that attaches to the front would not go on, but after messing with it for a few minutes it finally went on.
|
| Performance vs. Expectations |
The flow is not strong at all. If you put your hand in front of it, the flows gone after about 12 inches. I was disappointed because I thought it would of had a lot of flow (600gph)
|
| Value for money |
No I'm defiantly getting at least K3's next time

Exactly what I wanted in a power head
| Installation and Operation |
A breeze to install. Hydor cannot make it easier to mount the power head.
|
| Performance vs. Expectations |
The product is everything they claim it to be. I was amazed by the amount of water movement that was produced.
|
| Value for money |
I would consider this power head to be a great value for the money spent.

I originally bought 2 K-3's for my 75g tank. I felt that with those 2 ph's there was too much movement. I returned one of the K-3's for a K-2. I am very happy with the performance from both of these power heads. They move an incredible amount of water and they are relatively small. I think that the suction cup/magnetic mount is fantastic. I have nothing bad to say about this power head.

Great powerhead for the price!
| General |
I've got Koralias in multiple sizes, and love them! |
| Liked about it |
I love the magnet/suction cup mount - it stays put! This powerhead is also very easy to "steer." If I add a new coral, or need to temporarily change the flow while I'm working in the tank, I simply point it the other way. Many powerheads aren't so easy to adjust.

The little guard that fits on the end pops off pretty easily.

Great Powerhead!
| General |
This powerhead is a strong and reliable one. Pair it up with a battery back up and you can leave home without any worries on a power failure. The magnets are strong and wont scratch your tank. For the money, you cant beat them. |
| Liked about it |
Easy to setup
Great flow
Low power consumption
perfect length power cord
Strong magnets
Easy to clean
|
| Didn't like |
Can't be used on a wavemaker without chatter and damage to the powerhead

Koralia 2
| General |
The Koralia was my second powerhead and replaced my first and very cheap powerhead which blasted current in a thin channel, however this lasted all of 3 weeks and after cleaning and rebuilding I realised I'd just bought a cheap head as now the flow was wholly inadequate and still in a thin channel. Id read online about the koralias' and how the flow they produced was wider and more natural so i bought one.
Initially I was impressed by the ease of setup but confused by the lack of any adjustment to increase the speed of the koralia. After using the old powerhead I initally thought it wasnt workign when I didn't see a visible current however this is a different beast and within a minute i could see clearly what was happening. The Koralia draws in current from a wide angle and disperses in a wide angle creating a more natural flow which is distributed around the tank creating brilliant movement to my hammer and torch corals which I couldnt get with the last powerhead as it was all or nothing, blast or stagnant. The koralia is excellent for natural movement I only wish there was room for more user tweakability, maybe additional fans and a control to increase or decrease flow. There is however an attachment to decrease the dispersion. Again a great piece of kit that your lps deserve. |

Magnet fitting is perfect as My tank is in a tight alcove.
Natural non linear flow.
The suction creates additional natural flow into the powerhead.
Additonal piece for optional direct flow.
Sound levels are excellent.
|
| Didn't like |
The impeller fan seems so small and Im guessing with a slightly bigger fan there would be greater movement.
No optional fan sizes.

Hydor Koralia 2
| General |
I have a couple of these in my frag tank and plan on getting another for my 20 long. They are inexpensive and provide a decent flow for the money. Not quite as well build as some of the more expensive units but definitely good on a budget. |
| Liked about it |
Inexpensive powehead that moves a good amount of water.
|
| Didn't like |
Magnet could be stronger.

Good flow for 3 foot or shorter tanks
| General |
An excellent flow creating pump that is easy to adjust. The removable flow cone makes it versatile for more direct or diffuse flow. It provides movement well in a 36 inch tank but any farther it would be too weak. |
| Liked about it |
Powerful diffuse flow
Easy to adjust direction
Low price
|
| Didn't like |
Adjuster makes it somewhat bulky
After cleaning the impeller, it is somewhat difficult to get the housing to properly fit back together due to the flex in the plastic.
