Hi Dave and welcome to the forum!
Please give us a compete set of water testing results taken with a drops-based kit. Also, tell us what kind of pool you have, the volume and size of pump. Also, what all have you put in this pool besides washing soda and baking soda? Please list ingredients and not just "shock."
What is the copper from? What is the source of your fill water?
You'll need a good test kit if you don't already have one. The one we recommend is the Taylor K-2006 or 2006C (same kit, larger bottle of some reagents). If you buy it through the Amazon link in my signature, the Pool Forum makes a little money on the sale which helps us keep this form online. Only buy if the seller is Amato Industries, however. Some other sellers are substituting the K-2005 which you do NOT want.
Repost with requested info and somebody here can try and help.
