I have an external temp control for my heater, I have noticed that the end of the probe has started rusting. I think it is stainless steel on the end, will this cause any issues in my tank?
Hi its this one what do you think, i have read people dipping the probe in silicone.www.amazon.co.uk/gp/aw/d/B018K82UQU/ref=mp_s_a_1_1?ie=UTF8&qid=1479159427&sr=8-1&pi=SY200_QL40&keywords=inkbird+itc-308&dpPl=1&dpID=41DDkOS9WHL&ref=plSrchNot all stainless is created equal. Some stainless isn't suitable for salt water and will rust. If you are using a cheap heater controller, that likely explains it. Most of the cheap controllers aren't designed for salt water.
