Welcome to our forum.
Chad, it must be  in the atmosphere!  I noticed a few back as well.  I do NOT have ozone, so that is not a possibility for me.  And maybe I am just paranoid, but it seems to me that when I look at my jets from certain angles, there is a brown cast to them.  But if I look straight down, I don't see brown.  Scrubbing makes no difference.  I did not use metal gon with my first (only) fill.  The only thing I can put a finger on is my bromine was down for a couple of days when dispenser was empty.  It is fine now and shocked with MPS.  I will be inspecting for sure now looking for more.  Is this a Jacuzzi issue?
So what happened Chad? Â
Chad,A new development for me. When I put bromine in my cartridge inside the filter, I found brown flakes. So I will be calling dealer tomorrow. Metal?
