Hydor Korallia 1 won't restart

[philagothos]

I checked 20 pages of this forum to see if anyone else had posted on this topic and didn't see any, so apologies in advance if this is a repeat.

I picked up to #1s this week from an LFS. I put them on a Coralife timer and set them for half hour intervals. When I woke up this morning I noticed one of them would not run when it was supposed to. I did some troubleshooting to make sure that it was just the pump and not the timer. Even when plugged into a regular unswitched outlet, this thing would rarely restart on its own. Most of the time it would start off in reverse, back out & try again. But then, it would just stop trying alltogether. I had to reach inside the shroud to jump start it each time. Did I just get one with a weak magnet? Is this a common problem with the K1s? I know putting them on a timer like this is not suggested, but I've also seen several other people do it successfully. It's not in a room where the extra noise of restarts will be a factor, and I'm not too concerned about each pump restarting 24 times throughout a day (though I might consider 2 hour intervals if I can get it working right).

Thanks in advance for your input.

Nope... This is why they are not recomended for wave makers. It is recomended that they be used with seio controllers which do not shut the pumps completely off. I would put it back in, get it running and leave it running

FWIW, I have my 4s on a wave maker with 2 hours on, one hour off with a half hour of overlap and have no problems other than the occasional clicking, but a haphazard guess is that the 1 has a much smaller motor... Just aguess though.

The thing that bugs me is that one of them restarts faithfully and the other one will not restart (or even start for that matter) without assistance. I've put the one on continuous run for now and the other one on a 1 hour timer. Though I'm considering changing it to 12 hours at a time to coincide with the daylight bulbs. I guess part of the annoyance is that there seems to be a clear difference between two theoretically identical powerheads.

One was made on friday after lunch

i have regular hydor's, they rotate the water direction in a wide angle. Sometimes if the power is shut off for awhile then turned back on they tend to stick from time to time. They also sometimes just stick from use, but cleaning can help stop this.

Could be that the pump is gunked up somewhere. Try taking it out and thouroughly cleaning it. That has happened to me once with one of my HK 3s. I don't run mine on a timer however.

It did this pretty much out of the box. I think I'm with Hop, stinking break time reject pieces! J/k, but I'm thinking of either returning the weak one or trying to put a MJ magnet on it.
