Edwal Hypo Check (Liquid) - 4 Oz.
Your fix solution is tested by Edwal Hypo Check for silver saturation-related tiredness.
If the fixer is still good after one or two drops, there has been no damage to the bath.
If adding Hypo-Chek results in a precipitate that is hazy, the bath is full and the fixer needs to be thrown out.
