OK here is another approach that would work, the advice here so far looks sensible to me but here is another option.

From time to time on Canreef I have noticed Deltec hang-on skimmers for sale. This is what I would get if I were in your shoes. From what I have read they are very good, I was planning on changing a FW tank to sumpless SW and spent some time researching and planning. For now I would let the live rock cure with or without the skimmer you have. Give it a few months, there is no rush.

It is true that hang-on skimmers are not as efficient as in-sump skimmers. However IMO that is really only a factor if you want an SPS tank. If you go for a softie and LPS tank the corals will appreciate some nitrates in the water ie. less than perfect skimming. In fact there are corals (mushrooms and others) that I can't grow in my reef tank because the water is too clean.

So I would let the rock brew for a while, sit and wait, someone will sell a Deltec or other good quality hang-on skimmer. Meanwhile spend time reading and researching.
