Yeah, there's quite a bit more rock. Nitrates seems to stay around 20, not as low as I'd like, but not alarming either. I'm dosing Microbacter, Reef Biofuel and Kalkwasser which seem to help. The only thing that's died recently have been snails and couple emerald crabs, but I'm pretty sure it's the coris wrasse that's picking them off. He's cool enough that I'll put up with it.
