Mod for Koralias

Well, I've noticed that my K4s are not putting out anywhere near 1600 gph. It seems my old K3s actually put out more GPH. Are there any prop mods you can do to the K4s to help get more flow or is it time to switch to Tunzes or Vortechs?

 

you can always try a maxijet with a sureflow mod. that will pump out your measly 1600 gph mwhahaha

 

Can you take the prop from the maxijet mod and use it in the koralia? That would REALLY amp me up.

 

no clue

 

Hrm, maybe I'll go check out the local hobby shop to see if they have any RC boat props to use.

 

Yes you can put the prop from the sureflow in the K4. Use the whole magnet assembly as well.

This is what I did, the info is taken from my local site.

I have mod'ed my Korilia 4's and placed the first one in a 5 gallon bucket, the same way I tested my Aquaclear 70 mods. I aimed it up and it lifted the water about 3 inches very close to my AC tests. If you were to ask me which one puts out more flow, I could not give an honest answer. I do know the AC 70's were putting out a little more than 3000 gph, I bag tested them.
Because I have never mod'ed a MaxiJet, I did not have a modified impeller. I went to Sea Dreams and pick up a couple of impellors for a MJ 1200. I broke off the top and used a Dremmel to take 1/2 of the plastic out of the center of the magnet. I picked up a carbon tube from Tower Hobbies and stuck it in side of the magnet. At work we use stainless rod to TIG weld, and just happened to have some used pieces that fit the bill. This rod was used to center the tube and impeller during the glue process. I also used Dumas 3004 props, the ID was too big for the tube, so I took a piece of ridged air tubing and drilled out the center until it would fit over the carbon tube. Then I placed the prop over the plastic tube. All of that was a press fit.

When I placed it in the water the power head ran backward. I placed my hand over the out put of the pump until the prop turned the correct way. It had run for about an hour before I took the pics below. These guys are going on my Swirl Stein's, so this does not matter. I will use the little fish guards that come with the K-4's to keep from making sushi when the power goes out. Then I will restart them the correct way.

Here it is

How long has it been the tank? Was it like this from the get go? I just happened to watch this on youtube and thought this might help. Its a video on pump maintenance. But the above idea sounds good to me too. This just shows a really good way to keep your pumps up to peak performance. Hope it helps everyone. Later 50JC

6 months. I do not understand your second question... like what from the get go?
