27 Pounds Live Rock in 38g Nuvo Good??

OK, maybe instead of editing your first post to change it to a completely different question, you just post the new question at the end and change the title to indicate there's a new question? Otherwise, none of the answers are going to match the questions and no one else will benefit from the thread later.

As for the rock question, depends on what you're going to keep. If you're going to keep some fish, they're going to need more than just 2 places to hide. Add in shrimp and crabs & they'll need places to hide, as well.
