Costco carries the Clorox XtraBlue shock but I noticed it has .25% copper metallic. I've always been concerned about chemicals with copper, but not sure if this amount is not enough to do anything or not. Is this something to be concerned about with an in ground pebble tech pool?
Copper Metallic in shock

Assuming that’s weight percent, then every pound of shock added to 10,000 gallons of pool water will raise the copper concentration 0.03ppm. Add 10lbs of shock and you get 0.3ppm which is high enough to cause scaling. Any plaster/pebble pool is going to be very susceptible to scale formation because the surface is perfect for it and plaster pools tend to run higher in pH making scale more likely.
Stat away from products wIth copper in them. Copper builds up over time and does not leave the pool unless you exchange pool water for fresh water. Any minimal benefit from that tiny amount of copper is not worth the future headaches.

In other words, you will know that the copper level is high enough to be effective when you begin to get copper stains. LOL.
