Hello!
I have the full-set of probes in my system. pH, Temp, Cond & Redox. They are in the sump area of my tank, which is dark enough to cause calcium based filter-feeders to grow. Some of them grow on the sensors!

What is the recommended method for cleaning the probes? I have a friend who used Vinegar from the jug and left the probes in for 24hours. He said it worked fine, but this is not the recommended process.

What do you recommend?
