Not sure when the new HKs are suppposed to hit the market but they are much smaller than the originals & are reportedly using even less power.

This is the thread I was talking about earlier. There is a link to the american version that those ebay ones are mimicing.

I have a hard time believing that. A $10 upgrade takes the normal output of the MJ1200 from 250gph to 1200gph - 1700gph?
Call me skeptical, because I am...

tip:
nuthin' wrong with those old school MJ's.
If unmodded direct their outs parallel to (and just under) the water's surface.
Or mod 'em. It's too easy. Saw 1/2" or more off of their discharge nozzle.

I will do that...maybe tomorrow. I actually need to get parts for one of my old MJs. I know, I sound like a hypocrite, but this is for my water making bin. I swear! Really! :lolspin:
Well, if the MJ1200 really can put out that kind of flow, I wish I had known a few years ago. I would have modded the 2 MJ1200s I had in my 29g tank - in particular, I would have repositioned the head to much higher in the tank. I had my unmodded MJ1200 about halfway up, and clearly was not generating enough gas exchange where I had it.
Of course, that said, I had FAR too little flow in that tank (one unmodded MJ1200 for flow, and one for my AquaC Remora HOB skimmer). No wonder I was constantly fighting that tank (I did SO many bad things - I'm embarrassed to even mention them on RC).

I agree with Tom, mj1200s (or mj900s for that matter) are noisy with the sureflow mods and take more watts to operate than a K3. However the modded mjs put out a broader flow pattern IMO. I run both but prefer the K3.

kinda funny....

I have a pair of K2's that seem to be slowing down a bit. I took them apart and soaked in vinegar and it helped a bit. Anyways, a buddy gave me a modded MJ, so I took it out of my mixing container and decided I'd try it in our 37g (30"L), and half our unmounted corals took to flight!
I was amazed at the water they push.

I try to stay out of the store stuff but I am familiar with the Korallia, tunze's , and the modded MJ's as the store uses all 3 of them .. All are great options the modded MJ is gph/$ ratio the winner for sure but be warned it is un unbelieveable ammount of water flow!!!
