Iron levels at 5.9 ug/l rusty magnet?

[tokigami]

Hello,

i have been testing my Iron levels and a few months ago it was reading 6.1 ug/l and now it is down to 5.9 ug/l

i dose Iron in my system that is 360 gallon and i dose 5ML of red sea product per day. would this be enough to raise my iron levels so high? or would u think this is from a rusty magnet. i check all magnets and could not find anything..

did anybody ever find a rusty magnet and then check an ICP test how high would Iron read with a rusty magnet?

You are dosing way more than that detection - ug/L is parts per billion.(Because iron is rapidly depleted/exported this is expected)
No other iron source required.
