Dixon1990 Posted May 27, 2007 Report Share Posted May 27, 2007 DO Spirulina Discs expire? i was give a basically full opened container of Wardley Spirulina discs from a family member that had a tropical tank about 5 years ago and they dont have an expiry date on them. I used 1/4 of one and the water went a bit cloudy. Will they be expired? Quote Link to comment Share on other sites More sharing options...
Afrikan Posted May 27, 2007 Report Share Posted May 27, 2007 Not sure if they expire, I am thinking they would.. and even more so if the container was open... I would play it safe and biff them. JMO Quote Link to comment Share on other sites More sharing options...
