Or you could use the LEDs with T5 hybrid fixture. Yes that canopy height is more suitable for all T5 lighting in my opinion as well.
Although you are getting ready for SPS, if your system is new I suggest you not wasting any money on SPS in the beginning. Start out with zoas, LPS and once you can handle those and you have a good knowledge of maintaining your parameters and have coralline algae going, then look at SPS.
I know it’s hard not to put in SPS soon, but patience will be key to increasing your success.
Also once you venture into SPS, try to start out with stuff that doesn’t cost you a fortune. Add a piece of Montipora and see if it grows (if it doesn’t your tank isn’t nearly ready).
