So i'm looking at three options:
1) 35 gallon rubbermade filled with scrubbies
2) a 40 gallon breeder. I would try to figure out how to 1.5 to 2 cubic ft of scrubbies in and a deep sand bed. Would be a tight fit and I would have to figure out how to get it all in, but I think its doable (as long as some of the scrubbies are not submerged)
3) I found a used acylic 20 gallon sump with a calcium reactor and a skimmer. It has three chambers. I would add a drip plate and scrubbies to the first one and try to get a deep sand bed in the second. I'm not sure if it would fit in which case I would go with live sand covered by liverock.
Are any of these opptions a no-brainer?
By the way, that link is great. I'm still reading some of the articles.
