Red Devil Pinwheel SWC 180

[Bosco83]

I already have the white lightning pinwheel and when I took my skimmer apart to replace the pump I found that almost all the teeth have broken off of it. I decided to order the Red Devil pinwheel this time but which venturi should I use? I have the original one the skimmer came with and the one that came with the wight lightning?

Thanks,
Brian
