Clearwater Scrubbers - Anyone run one?

[Spanky05]

@FLSharkvictim @lion king @Tmcgoo13 @PmCarbrey @BoomCorals --Any update on your experience with CW scrubbers?

@Bpb , @dragon99 and I were talking about these earlier

Also, what size scrubber are you using on what size tank?

I have a 90gal and debate if I want the smaller or medium option.

Thanks!
