My guess is that either your 70% wasn't made up properly and was a higher
concentration or it's been so long since you've changed the solution that
the water is fully saturated with the formalin salts. If it becomes a
regular problem, you might consider reducing your first alcohol's
concentration to 60% or even 50%. Good luck!
