I decided to clean my sump for the first time in about a year and something caught my eye. I noticed my eshopps probe holder magnet (which holding my dosing and ato tubing) completely rotted out and disintegrating into powder. I always kept this a few inches above my water line in my sump but when I feed my tank I turn my return pump off and the level raises to above my probe holder. So it was make contact with my tank water a few times a week. I had some coral die off a few months back and maybe this is related to it and maybe its not.
This seems to be a well known issue but I just wanted to share.
I ordered a cheap acrylic doser tube holder off amazon and used some weldon to attach it to my sump. Problem solved.
