As for the Koralia mod; It's pretty simple. Normally there's about an inch gap between the impeller and the end of the berring shaft. So if your Koralia is facing down the impeller could slip out a bit, causing it to bounch around upon activation right. Well, just cut a piece of rigid water filter line 1" long and place it in there. As shown in the pic with the yellow piece of tubing.

Hey Danny,
Here's the links to two pages that talk about modding a MaxiJet and how to keep it from starting up backwards.
On reefchili - simplebuild there is a questions page
Common Questions that has this description of the stopper:

What is the stopper and how do I use it ?
Because the maxi jet runs on alternating current (AC) power it can spin both left or right and will do so randomly
when you first plug it in. if it starts going the right way then perfect but half the time it will start going the wrong
way and end up sucking water in the front and blowing it out the fins on the side. This is where the stopper
comes in. the stopper is simply a piece of acrylic rod shoved through the side of the housing. I drill a 3/16” hole
about a 1/8” below the top of the housing (just under the cap) and glue a ½”-1" piece of 3/16” acrylic rod. What
happens when the pump starts the wrong way is it pushes the whole impeller up towards the cap when this
happens the prop will slam into the stopper (acrylic bar) and bounce back the other way and start running in the
right direction. This is extremely easy to implement and works very well. Some people have found with the
octura props that you don’t need a stopper because the ends of the prop extend up and actually slam into the
centering cap itself. I personally always use the stopper bar because it works so well , costs almost nothing and
takes about 20 seconds to install . Mother always said “if it an’t broke don’t fix it” : )

Oh yeah, don;t try any of the links to
www.mjmods.com, they don't work?!?
There is also dhnguyen's DIY build on ReefCentral
The "Hitchhiker's Guide" to the Maxi-Stream mod that goes into a bunch of detail on the MaxiJet mod, but he has a different take on how to make a stopper and there's a bunch of pic's on these pages of how and where he puts the stopper.
I think maybe a mod of one or the other of these stoppers could work for Koralia's and let us use the wavemakers.
