New version of Koralia PH

[Spotted]

Hey guys I've got a question. I've got 4 1040 Koralia Evolutions that run on a wave maker and I am having trouble with them. I've had 2 of the little rubber bumpers in the front of the cage break off. It's that little thing that keeps the blades from spinning backwards. Well, with that thing gone, they run backwards. Hydor sent me replacement cages for them which was great, but one of those replacement cages has also broken. What PH have you had no problem with that can run on a wave maker.
Thanks!!

Oh, I should also add that I don't have tons of cash or I would already have a set of Vortechs. LOL

When mine ran backwards, I unplugged them and plugged them back in. That corrected the problem.

These powerheads are AC/DC and not direct current, so there's a 50/50 shot of the PH wanting to start in reverse.

I had the same issue before I realized a cage was on incorrectly. I now also run the Koralia wave maker with 2 1400 evo's in my 55, and since I replaced the cage have had no issues with running in reverse. You will, however, hear a clicking sound the times they do want to start in reverse., as the blade will bounce off the bumper. I have mine set to switch between 1 & 2 every 3 minutes and have not a single reverse start up for the 2 months I have been running it. So just make sure the cages are on properly and that the rubber bumper piece does not fall off. I saw online replacement cages for just a few dollars, so maybe buy a couple for back up, even though I have not needed to replace mine since...

Why is my Koralia Evolution running in reverse?

There are several possible causes of reversal in the Koralia Evolution.

1. The bushing that sits inside the black wing of the impeller may have slipped down. If this has occured, simply push the bushing back into place. You can also contact Hydor USA Customer Service and request an upgraded bushing that snaps into place, preventing slippage.
2. The front cover maybe damaged. If your cover is damaged, you can contact Hydor USA Customer Service and request a new cover.
3. The rubber bumper on the inside of the front cover maybe missing or damaged. Hydor USA Customer Service can supply you with replacement parts.

If you cannot diagnose the cause on your own, feel free to contact Hydor USA Customer Service for assistance.
