Hi, there are many brands of beckett skimmers available locally. You can contact the local sponsors for more details. i.e. I-aquatic, Reef Manic, Bio Ocean etc.
As for tunze, you can contact reef deport.
For your pump, what's the purpose of it?
For return, IMO Eheim, Aquabee are very good return pumps.
For beckett, use Iwaki or Resun.
