I have done IPSF numerous times. I coupled diversity with micro fauna & fana with Tang Heaven Red by the pound.

While you would not need nitrification bacteria, everything else in that kit will work to the benefit of your sandbed.
Since then, I achieve this biodiversity when introducing diver collected live rock. From my perspective, I want to maximize the complete benefit of biological filtration by using this sustainable source of live rock. In the early 1990, a handful of visionaries purchased long term lease rights west of Tampa in 30’ of water and placed 20 million tons of limestone from rock quarries inland.
I also suggest getting live sand from live_plants which is GCE, GulfCoast EcoSystem.
