Can algae ball be reused?

Hi All,

I have just finished an experiment using algae balls. It seem such a shame to throw them away. Can they be reused?
 
Yes! I've had some sitting in the fridge in distilled water for over a year now. They dehydrated completely during the first lockdown - I soaked them in water for a couple of days after that and they still worked (after a fashion).
 
I have too!
I rinse them with distilled water afterwards and then store them in distilled water in the fridge. Test them before they go again but mine worked fine for almost 2 years doing this - just remember to take them out the fridge before the lesson so they have time to warm back up

Thanks for that, good to know. In the fridge they go!!
