I'm wondering how to keep the pH, ORP and conductivity probes clean from bacterial or algae overgrowth?
I see a problem especially with coralline algae and those little hard feather worms that both like to settle on smooth glass or plastic surfaces.
What cleaning solutions are suitable to kill and remove any kind of growth without messing up the calibration?
Would NaOH (to remove algae and all other organic contaminations) and then HCL (to remove calcium deposits) be recommended?
What are the recommended cleaning intervals?
