Broken front case on Koralia Evolution - 750

Jerzy · 02/28/2012, 01:47 PM

Was wondering if anybody else had a problem with the Koralia Evolution - 750
front cover breaking. I have 2 of them running on a red sea wavemaker. On the front is a little rubber bumper on the inside near the blades. Both of my powerheads broke at the same spot about a month apart. They seem to work ok, I can see a little wear on each of the rubber pieces. They are only about 9 months old. I guess you get what you pay for...

So far I haven't had any issues with mine. I've got a 1400, a 1050 and two 750s on a JBJ Dual Wavemaker. They've been running since the end of December, so only a few months. They make the occasional click on start-up, but read that is normal.

Did you try contacting Hydor? I've contacted them just for questions and they were very helpful.

I did send an email to them a few days ago...was looking for their phone #, wasn't on their web site.

i have been lucky so far but have read some issues on them breaking. everyone has said that after contacting hydro that they sent them replacement parts at no cost.

Jerzy · 02/28/2012, 02:27 PM

Do you think it hurts to run them that way?

griss · 02/28/2012, 02:30 PM

I have 3 750's and two of them experienced this same breakage. I contacted Koralia via email and they sent me three new parts.

oki_reefer · 02/28/2012, 02:32 PM

i would run it but make sure that the cover can not become displaced. dont need a fish getting cut up.

dieseldaisy · 02/28/2012, 02:45 PM

Just spoke to someone at Hydro. Sending me new covers. I wasnt sure what the bumper were for, told me they keep the impeller from running backwards.

Jerzy · 03/15/2012, 01:39 PM

Just a quick up date...I did get new front covers from them but only after having to call them several times. I sent them emails as I was told the first time I called, but never got the replacements. Never even responded to my emails. Best to call...

1 of my 750's did break just as described. I called them and they sent me out a new cover. A few days after getting the cover, the other 750's cover broke. I have an email into them. So, far my 1050 and 1400 are still OK. I wonder if it's just the 750's.

Are the replacement covers a new design? If not, they'll probably just break again from using these on a wavemaker.

TimeConsumer · 07/01/2012, 08:20 PM

I've had four of them break in the manner described due to being used with an on/off wavemaker. It just made them start backwards instead. I kept them like that until I moved on to Vortechs.

falconut · 07/01/2012, 08:26 PM

Not sure if the new cover are a new design, but they haven't broken. Replaced both 750's and they're going strong.
