I think mine has finally died it's just the stock 130 skimmer whY else cN I use I know the tunz but I can't afford one now. Would I Be able to use a rss sea prizm or a Vecton 400????
No idea on the 400, but the prizm I don't think will fit and I've heard it's not a very good skimmer anyway all things considered. You could try and find a used 9002, personally I would try to go that route. If your stock skimmer died you could get replacement parts to get it back up and running, contact red sea.
