Koralias breaking

S

Squirt

I have four Koralias running on a Red Sea wave maker. The problem I am having is that when the timer cycles through, the magnet/propeller smacks back and forth on the pin until it spins in the right direction. This impact has caused the front grill to snap off in all of my koralias after a period of a few months. I have tried to add a bit of tubing to restrict the front to back motion of the magnetic propeller, but ultimately, the front grill (which holds the pin into the housing) has again snapped off. Epoxy isn't durable enough for repairs, it broke again.
Ideas? Would a regular powerhead spread out the flow enough? I do not have the budget for vortech, unfortunately.
 
I don;t know if it will work with yours or not, but I used some small ortho braces rubber bands and wrapped arund the shaft to keep it from jumping like it was. It was enough to stop te propeller from jumping in and out like it was. Thanks to my my daughter, I had a whole bag of the tiny rubber bands.
 
or run then with out the wave maker, i had had mine one my ACjr wave maker and they never broke just made a loud noise for while? thats why they sell a wave maker for those?
 
Hi,

I would suggest going with the tried and true maxiet's with one of the sureflow type mod's.....turns a lot of water.:D

Cheers,
 
Only the controllable K's are designed for the abuse of a wavemaker. Ron makes a good recommendation, get a few MJ1200's with the sureflow mods if you are married to the wavemaker. They are really the only low cost pumps that hold up over time on a wavemaker.

I think the pumps, kit and magnets will run you about $75 per pump and will push a LOT of water.

Send your K's in for repair after buying the MJ's and then sell them :)
 
Also check with Rick, he may still have a few new maxijet 1200's for $17.50ea. That would cut your cost even further. :D

Cheers,
 
The Red Sea Wavemaker should not be used with regular Koralias. I put mine on that wavemaker and they eventually started running backwards and would not start right all the time. I had to unplug it and replug it until it started right. So I got a SEIO controller and put the Koralias on them, and they worked GREAT, never had problems then. I also modded my Koralia with the Sure Flow Mod and that thing turned into a BEAST. I eventually took the Koralia off the wavemaker and ran it as normal. I still use the Red Sea Wavemaker but only with modded MJ 400, MJ 600, MJ 1200. they chatter every once in a while but that is when you clean them.
 
On the k powerheads most of them if you use something to keep them from jumping they will run backwards, that is y they jump is to get in the right phase rotation so they dont run back wards.
