i believe its called the "orp probe" for a Red sea plus redox and ozonizer model number 331. someone told me most of the probes are universal. i want to make sure i have the right one because the unit is probably from 1995. i wanted to see if any of our vendors on here sell them or a site that has the correct one i need.. it has two circle prongs and one slightly smaller prong that plugs into the unit, so 3 total. i think the prong is broken because everything works fine on it but its saying my levels are like 450 and keeps moving around from real high and then real low. so i think the probe is bad, and it looks real old and crusty too and was never replaced so its gatta be shot. any help would be great! thanks
here is a picture of the unit
