I have two Turbelle Nanostream 6025's purchased November 2020. They were starting to get some algae film so I took them out and cleaned them by soaking in citric acid + RO water mix. After putting them back in the tank, one makes a faint radioactive click sounding noise while running, at all times.
I will try to take a part and put back together again when I have time, but any idea what would be causing this?
