Has anybody ever made an attempt to clear SIBO, candida, biofilms before an FMT?

I'm attempting to rid myself of all of those problems over the next 6-9 months. I'm also taking abx(which causes candida) for 5 more months. My plan is to start with a "clean slate" and then do an FMT afterwards but would love to know if anybody else has done/heard anything similar?

re:Lindyap. Did your rheumy or anyone else explain why they chose to use antibiotics prior to treatment? All of the clinics I look into do the same but I can't make sense as to why. Can we not assume that the abx will make it tougher for the probx(fmt) to colonize? Maybe they want a "clean slate" as well? But what are they attacking with that abx? Do you know which kind of abx you used?
