and crushed coral.
What else could I be missing?
I have only added two hermit crabs at this time.
I don't plan on adding any fish till the end of the month (which is about 4 weeks)
Actually, this isn't a bad setup at all. I would personally remove the sponge filter and instead use activated carbon. Also, the term crushed coral is very vague. Is it aragonite? Or crushed "oyster shell" coral? Or is its actual crushed coral?, which looks like aquarium gravel, but it is white and chalky.
Removing the sponge is important, because the sponge is biologically active and results in Nitrate buildup. By using only live rock, aragonite sand, and a protein skimmer, you can remove waste directly without the buildup of harmful Nitrates.
