I just purchased a Jebao pp8 powerhead. I had some difficulty finding a comparison between the Jebaos and Koralia products. Hopefully this can fill in the gaps. The price between the two is about the same $60 +/- $10, purchased online. The Jebao comes with an attached controller which varies the flow and programming, e.g. 50% in a pulse pattern. It also has a "feed" mode which pauses the jets. I don't know if I will use it as it seems only fair to make the fish work a little to chase down their food. The Jebao can be angled in all directions as can the Koralia, albeit by a different means. Both move a lot of water. Many have complained that it is too much. At least on the Jebao you can turn down the power if you wish. I have (had) them both on a standard 4 foot 75 gallon tank, which seems appropriate. I would not want to go bigger nor smaller.
I only tested the pp8 as a single unit, but apparently they can be linked and synced for some cool wave features. I have read that keeping them synced was an issue with the rr series and I don't know whether it has been improved with the updated pp series. The pp8 shipped to my house via Amazon in 6 hours free with Amazon Prime. Amazing!
In my opinion, there are 3 critical distinctions.
1 - as mentioned, the pp8 has a built in control, which seems cool.
2 - the pp8 is significantly smaller yet produces the same or more water movement. It is about 2 inches closer to the glass. See picture below.
3 - the Koralia offers a stronger linear flow while the jebao is more dispersed, put still quite linear. Both move a lot of water.
I also own a Hydor Koralia Gen 3 which mounts closer to the glass. The head is much bigger than the pp8. The flow in the Gen 3 is very dispersed and hardly seems to move water. Moreover, I could hardly feel the water move 5 inches from the power head. Frankly, I don't get the appeal since I like the Evos better. You can see the Gen 3 in the back right side of the tank.
In the far left corner is a Koralia Evolution 1150, which is a good pump and a little smaller than the 1500.
I cannot offer a longevity test for the pp8. I can say, however, that I didn't get more than 3-4 years from the Koralias. I really liked them for the price, albeit when I first started purchasing Hydor powerheads, they were $35-40, not $50-70. I cannot compare them to Tunzes as I don't own one. However, they appear to be very similar in design.
