The below information is my personal assessment of the Koralia evolution powerhead.

Overall Size and Appearance

Although they are not a eye sore in your aquarium, they can be larger than other comparable powerheads.  The Koralia evolution powerheads are a little large for my personal preference, but that would not stop me from using them

Mounting Set-up

The Koralia evolution using a combination of a suction cup and magnet mounting system.  I personally do not like using any powerhear with a suction cup in the mounting system as over time, the rubber on the suction cup will fail 

Flexibility of Adjustment

The Koralia Evolution has limited angles you can adjust the direction of the flow.  This may or may not be a limiting factor based on the needs of your set-up.

Ease of Maintenance

These powerheads are easy to take apart and clean as apart of your routine maintenance.  I have been using two Koralia Evolution powerheads for a few years now without a single problem.  They are highly dependable with properly maintained


This is one of the best features of the Koralia Evolution powerheads.  They are among the lower priced powerheads commonly available in the hobby.  .

Likeliness of Recommending this Powerhead

I would highly recommend this powerhead to anyone who is on a tight budget and only needs fairly straight flow coming from the aquarium wall the powerhead is mounted to.

The Koralia Evolution powerheads also come with rubber posts built into the base to help prevent noise from vibration.  Although I have never noticed any vibration coming from any of the Koralia powerheads that I have used in the past years, this is a nice feature to have.
