New Koralia Evolution powerheads.

[Interior_Reef]

We have sold several of the controllable koralias, and all of our customers have had nothing but good comments about them.

I have the GHL Hydor controller, with 2 x K4 controllables, running off my Profilux, and 3 x Evo 1400's. I am very impressed myself with all of the recent powerheads from Hydor.

Update on the evos:

One of them stopped working and another one clicks. The two other ones are working fine.

I tried my kora's on a cheap wavemaker timer, worked for about a day, then they wouldn't start. I noticed the reverse start sometimes too. I'm interested to see how this goes.

I picked up two of the new 4's for my frag system a few months ago. I did some reading on RC and the general concensus is that they should not be used on timers so I've just left mine running constantly.
