I know this is known subject.. But I just purchased 2 jebao wp40's for my 6'reef. I played with them for an hour. Got them set so the current is good.. But now I can seem to find a happy spot for my low current corals.. 2 brains. An elegance and a gargonian.. How do you guys set yours? My tank is sps dominant.. But still have those low flow corals.
