What type of media and reactors for reef?

[Daddyrawg]

My 90 gallon is cycling.. I am looking into having a Reef setup..
Should I get reactors and place in my sump? if so, how many and what should I use for media? when should i run them? 1 reactor or 2? what is necessary for an awesome healthy tank? carbon, gfo, biopellets? I need clarity

Nada, unless you have an algae problem (GFO as phosphate remover in GFO reactor) but you don't know that yet. For clarity, use a filter sock and clean it often. Any stoppage in the water flow can increase nitrates, which are not your friend. Your live rock and sand will support bacteria that do the job of ammonia removal, if your fish load is smaller than the processing capacity of your rock and sand. You do need a good skimmer, one for about 200 gallons. But that won't have any work to do until your tank has been running about a month. Don't run carbon unless you need it (soft coral). Just let the tank do the work, and read the sticky notes atop this forum.
