There is the potential need for a better skimmer with this type of tank, i always suggest aw skimmer in smaller systems thawt will handle twice the tank volume (INCLUDING SUMP VOL).
VHO lights are cheaper and have fewer long term issues for octocoral systems if you don't do SPS spp of corals, although you can do a few SPS spp with enough
VHO lighting (4 TO 6 BULBS) down the road.
Comments about alleopathy with chemical anti-calcification terpenes will still apply, so expect an occasional sudden death in SPS specimens in such a mixed tank that occurs for no apparent reason (and stunted growth of SPS SPECIMENS.)
Plan to use carbon 24/7 in tanks of softies to keep the water clear and to drop the alleopathic interference between corals to a minimum...
