nstead of doing a PVP / betadine dip or Revive - (which Revive is great for softies/ LPS but is quite stressful to Acropora)
Id recommend sourcing some food/USP grade potassium chloride, it's very safe and the least stress inducing dip for Acropora Bulk supplements is a trusted brand, dissolve 1tblsp/ 16g in 1 gallon of aquarium water and dip with light basting for 7min, if there are FW present you will see them come off pretty quickly.
