Welcome to our forum.
My neighbors gave me their old pool cover. I cut it into several hot-tub sized squares in order to use them one by one, over the years, as a spa blanket.(The cover was only a year old--they had neglected it, left it outside and it tore, etc. So it is not old and worn out from use--I cut off the good parts to use and it is like new)I have been noticing a slight discoloration and figured that it may have been an old leaf stain from it's pool cover days.Today however, I really noticed that it is a nice roundish, brownish spot, directly over my ozonator! The rest of the cover is spotless and looks a bit bleached out on the bottom. The top is fine--it is just brown in that one spot on the bottom. I wonder if I had not been using this spa blanket, if my cover would have a brown spot on it? :-?Do you think that the spot is from the ozone, the heat that comes out there as well, or a combo of the both?
When I spoke with Artesian tech support, they had told me you will see a brown circular discoloration on the underside of your cover above the ozonator port. If you have the upgraded propure system (which is a chamber system for artesians) the discoloration is alot less noticeable if noticeable at all.

It wipes off easly. I don't see any brown on the underside of my cover. Does the brown discoloration on the blanket wipe off? Anyone now exactly what this brown discoloraztion is?
do you have a high metal count in your water(irons etc)? Chances are the brown discoloration is being caused by your ozone system oxidizing the iron in your water? This is why you see it most prominately after a water change. Get rid of the iron and you should get rid of the brown slim. Looks like your ozone is working!

I would have to double check, but when I looked up my city's particular water testing on-line, everything was way below "notification level". In fact, numbers were so low that a while back, I posted about the necessity of using Metal Gon if there were no metals to be gone!A few of the crew here said that the $8 bottle was cheap insurance and to just use it. Due to the great info from all of you here, I did NOT even follow Chas' Law! I got my tub July 4-ish and have yet to change my sparkling water. I'd sure change it more often if I didn't HAVE To add $8 Metal Gon and $8 Spa Down (almost whole bottle) at every fill. Anyway...IF I have ANY metals/minerals, whatever, iron is NOT one of them. This "stain" has been gradually appearing on my pool cover spa blanket for the last 3 months. I can't remember when I first noticed it. It is directly up above from where the ozone/heated water outlet is. This outlet is on the very bottom of my spa.No slime, no ring, just a rust/iron colored stain on the blanket.
