I'm in a pickle!!!

[Gools]

Well I've got a dicision to make, and I can't decide. So tell me what you think. I have a 205 which I'm thinking of setting up. But I don't know wether to set it up to my excisting 180, or set it up on it's own. If I set it up both together, then I'd need to buy a pump, which I've been debating the dolphin amp master 3000. Or if I set it up on it's own I will need to buy myself a new skimmer, which will be in the same price range as the pump. So what do I do?
