My first reef (90g)

[Dragonsteeth]

When i set up i used a Lee's in tank protein skimmer (needs air pump) for cheapness. It worked fine and did the job. I only upgraded it after 3 years to take my tank to the next level.
If you lived nearer you could have mine.
I only have a 33G tank so i dont know if you can find one for bigger but it might get you going.
Also, better to bite the bullet and get all your uncured live rock in there now so that when the cycle is done you are ready to go. Otherwise you will have to add cured rock at more expense each time unless you add one small piece of uncured each time.
This is the limit of my experience. More experienced auarists could give you better advice.
