Great point Brad!
Just to reassure you Justin, in the beginning of my tank I had (sadly enough) an eheim 2213 and a fluval 404 on the tank. After doing my rookie research I decided I had plenty of live rock and disconnected them one day. Tank didn't even flinch or miss a beat.
No spikes in any levels what so ever.
