I always have to look it up too before mixing a new batch. From http://www.reptilebasics.com/F10SC-100ml

The recommended dilution rates of F10SC are:


  • General disinfection at 1:500 (2ml in 1 liter of water)
  • High level disinfection against bacteria, fungi and most viruses at 1:250 (4ml to 1 liter of water)
  • For use against the most resistant viruses such as Parvovirus or PBFD at 1:125 (8ml in 1 liter or water)
