You used established/cured LR from the LFS correct?
There should have been little to no "die off" durring the trip home, especially if you had it in saltwater. Meaning curing isnt needed. Plus your already 4 weeks into this. Looks like your spike already came and went. Its now on the down slide, in fact Im betting your pretty much bottomed out now.
Add your small CuC and even a fish or two. Your ready.
My Dads' 29g cube project had a light load of 1 shrimp,5 hermits, 5 snails, and two damsels from Day one(I objected of course). He used LR straight from the LFS to the tank. The cycle has already peaked and is now on the down slide after 2 weeks. Everything lived! It was a really gentle cycle.
Using LR from the LFS or especially an established tank makes the cycle go much faster. Looks like yours lasted barely 4 weeks.
My 125DT cycled in two weeks, but I waited almost 4 just in case.
Moral of the story, I give you a green light for about a dozen mixed(cheap ones, no need to put in the $40 shrimp) inverts. And one or two SMALL fish you have on your stockist. Start doing your water changes, and your good to go.
PS, blue chromis are awesome fish. Good choice for cheap starter fish. I have 3 in mine. They are the goldfish of the sea. Will live in toilet water ^_^
They are super docile! They're version of fighting is to turn around and kiss each other. The one with the biggest mouth wins, and gets to lead the pack. I call my trio the noob crew.
