wavemakers and powerheads

[salvini55]

Are Korilias and Maxi jets suitible for use with a wave maker? Which one is better.

Thanks for your opinions

im using both over a year now. no issues

If you goal is to generate an actual wave like a wavebox then no.

What size tank do you have and what are you trying to accomplish?

Koralia are generally not considered to be good to use on a wave maker.
MJ's work very well though and there are TONS of cool mods to make them work even better.
My wave maker I am assuming of course that you mean a power bar that turn them from full on the full off.

Koralia does have the controllable pumps but they must be run on the koralia controller as they are variable AC input.

I dont have a goal as of yet, i dont even have a sw tank. Im thinking about buying the 75 gallon from saltynewb and a coralife super skimmer 125. I have a 33 gallon sump. I was just wondering about current flow, a controller would be nice but too much $$$$.

Yes i am talking about the power bar. I read the other day that on and off cycles can be harmful to the powerheads. I was thinking of using korilias but now it looks like ill use MJ's.

There is a mod, really easy, you can do to your korillia pumps to help them with the on-off cycle noise.  I still do not advise it but I had done some research, mainly on this site and reefcentral, and the conclusions were mixed.  There are enough people using korillia's in this manor that made me think it was ok, but there are far more who use the MJ's, and the associated mods, it was hands-down the best option.

If you need to use korillia's, take some stiff air-line tubing and cut a piece about 1" long.. use the small diameter .25" stuff if you can find it... Then disassemble the korillia pump/impeller... put the tubing on the exposed shaft, not on the magnet end... then put the system back together... what you end up with is the tubing holds the blades back against the magnet/impeller/drive unit so it doesn't bounce and make all that noise that you get on powering it up...

ahh smart, and easy. Im going to look into these MJ mods though. any good links?

Since these sureflow kits came out alot of the DIY and simpler DIY kits have dissapeared:

Here is the link to the mod I used.

The Maxijet impeller is designed to reverse direction each time the powerhead starts. By cutting off the nozzle it allows the flow of water to change direction each time the powerhead restarts. I had four Maxijets hooked up to a wavemaker and produced eight differrent flow patterns.

Also, by drilling holes into the impeller cover you can increase the flow rate substantially.

Good to know! I didnt understand if what your talking about was a mod at first but now i understand sorta'. even with the impeller reversing each time it cycles, would it not still flow in the same direction? (out the hole you cut?)
plz explain

Thanks for the links guys!

too me it sounds like that u start the pump and its pushing forward, then u turn it off and u start it again and the pump isn't pushing anymore its sucking in. like going reverse on a boat. and drilling wholes in the cover would be pretty kool too!

When the nozzle is removed it creates a very wide path of water flow favouring either the right or left side depending on the direction of the impeller. When the impeller reverses the water flow changes direction.

Picture a clock with the nozzle pointing to 12:00, when the impeller is running clockwise the water flows between 12:00 and 3:00. When the impeller is running counterclockwise the water flows between 9:00 and 12:00.

ohhh ok i get it, i didnt think it would have a noticable affect. this is probably the way ill go. sure costs less than a sure flow

I tried something similar to my korillia, only problem is that it stops the impeller from coming up and hitting the 'break' that forces it to go in only one direction.  so just like a MJ on wave makers the startup direction is different each time.  however if it can't hit the break then it will simply go in whatever direction it starts in, which sometimes is backwards.

hi,
if you need a skimmer i will have one for sale ,its a used one it works fine a Coralife Super Skimmer 230 if yrs interested pm me back

[salvini55]

wanna trade for my coralife ss 125?
