Some possible triggers of infection are:

- Temperature spike
- Salinity spike
- Low dissolved oxygen
- Poor water quality related with phosphate levels up to 5 ppm
- Addition of sand
- Changes in brand of salt
- Bad test kits giving faulty results
Sand will raise silicate level and possible change to phosphates.Actually I did add sand about a month ago. I kept getting bare spots bc the figi pink blows all over the place so I added crushed coral to the bate spots but didn't remove any old sand
