First you must do a bit research here as it is not a good idea to mix the soft and the SPS as the soft corals wage a chemical warfare against SPS. The mix of SPS and LPS is okay but difficult to balance the correct water flow for each. The SPS require a high flow and the LPs in general like a gentler flow.

Alan thanks, needs some more advice.
I have looked at a number of setups and quite a few of them have soft corals mixed with LPS and/or SPS. In most one type dominates.
What I understood from literature, if you run sufficient (a bit vague term) skimming with intermittent carbon filtering the war can be managed?
I intent to start with LPS only and allow them to establish them self over a six moths to a year period. Once they are growing well, I will add the softies, and hopefully they will then not overwhelm the LPS.
Not sure what I should do with sporadic growth of any softies from the live rock if it happens during the start-up?
Will only add one or two SPS right on top if I get everything stable?
PS. Do you classify anenamies as a soft coral or is it completely separate.
