Seems good to me, too. If you haven't had a low pH (<7.0) in the past, the copper is NOT from your pool, but IS from either your fill water OR something you've put into the pool.
You can use HEDP to temporarily fix the problem:
HEDP is a liquid phosphonate that is pretty chlorine stable, and very good at keeping dissolved metals IN the water, instead of ON your pool surfaces. It can lift recent stains, OR it can be used along side of ascorbic acid, to keep the metals in the water, after the ascorbic acid is consumed by chlorine.Jacks Magic The Pink Stuff 1qt (60% HEDP) @ Amazon

and the CuLator product to actually REMOVE the copper from the water:
The CuLator product is a special patented plastic material, contained in a bag that goes into the skimmer, that can slowly take metals OUT of your pool water. We think it works, and have some evidence that it does, but not proof yet. (Not likely to be available locally.)1 ppm Culator @ Amazon

but, you need to get away from that BioGuard dealer. They screw up pools more creatively than anyone else out there, and pioneered the use of chlorine+voodoo blends that do 'who-knows-what' to your pool. Get a REAL testkit:

and take control of your pool!
