wow bud, i say this with my ozzy "i could be nice & not say anything, but then again, that really would be rude "no offence" tag",
What you got going there, is a pretty dodgy piece of equiptment bud! . On the bright side you have impecable finger nails.
lol
I wouldn't worry, i use some of the jap crap myself, strange thing is it keeps a man full on rice for a day & the units are cheap enough to replace any part without even battering an eyelid, go figure!
Simple set-up bud, the power heads alone are cheap, well here they are, maybe not in the states, so testing with various methods wont cost alot of damage to the hip if it stuffs up. The design basicly interupts the vortex chamber to begin with so i wouldn't stress a great deal. If you are going to tinker, i would prob buy/ demand that 12 blade thats mentioned on the box, or simply drill holes in the fans, Notch out seams on the thread of a long gater clip, (tie fasterner?). put through all of the holes, then bend the notched bits in alternating dirrections & be done with it. create an absolute monster that will eventually shread the shelding of the extremely close impellor surrounds.
lol, hindered more than helped, but at least ive done my bit for the asian ecconomy today..lol
