ninjamyst Posted June 26, 2016 Share Posted June 26, 2016 I bought Korallen-Zucht ZEOvit Nano Power Pack 1.5 years old. It says best used by 2/2016. How valid is that??? Do supplements in general really expire? What if they are unopened, unused? Link to comment
CronicReefer Posted June 26, 2016 Share Posted June 26, 2016 Most vitamins/proteins degrade over time, especially in the presence of oxygen. I wouldn't think it would poison your tank but it probably wouldn't be useful anymore either. Link to comment

Pjanssen Posted June 26, 2016 Share Posted June 26, 2016 psh. I'm sure they are still good if they haven't been opened, exposed to air or heat. Possibly not quite as potent, but not bad. Link to comment
