New Spa, Brown/Yellow Water

[Hikerboy1990]

Just started a new 350 gallon spa.
Ph was high, 8.2 brought it down to 7.2
Alk was at 80 holding strong.
Added my Chlorine and I was at a 2 - 3
Went to bed, and this morning I woke up to a brown/yellow spa with a ring of what looks like a rust colored dirt.
Whipped that off and took a water sample to my local store.
Everything looks good but she thinks I have metals.
Added the correct dosage of Metal Free (Leslie's)
I have been running and rinsing my Filter for the past 6 hours.
My filter is getting rust colored.

Is this metals? Or am I wasting my time and money?
How long does this process usually take.

P.S. I am on Well Water, but i do have a 2 stage filtration system.

Any advise would be awesome.

Welcome to TFP and congrats on the new tub.

Looks like iron to me, but I'm not the resident metals expert. Here is an article from Pool School about it,
Pool School - Metals in the Water and Metal Stains

Here is an article about how to maintain your tub, we've been maintaining ours this way for 18 months and are very happy with it.
How do I use Chlorine in my Spa (or pool)?

Metal Free is designed to bind to and precipitate the metal so that it gets caught in the filter. Since spa circulation is pretty fast I'd expect it to clear within a day. You will need to clean the filter and may need to add more Metal Free. You could consider using a pre-filter attached to your hose when filling as another alternative to getting the iron out.

The only problem is when I got the water tested it didn't test positive for Iron or Copper. That's my only concern. I have also been cleaning it out ever few hours and I am not noticing any difference
