For starters never judge a LED Fixture by watts.
Back in the day we grew corals with a 250 or 400 watt MH... Serious growers laughed at the guys with 175DE MH....Unless it was on a Nano...
Choose a Fixture that will give you 200 PAR on the sand bed before you consider SPS.
Also Flow, Skimmer, Reactor or Three Part is the min.
Keep your animals happy...
