Help! Last weekend I must have “overshocked” with Clorox ExtraBlue2. I went to flush my filter this morning and the cartridge had a blue hue to it. I went to the local pool store and my test is way off. The copper is 3.5 ppm and should be 0-0.2ppm. pH is way off at 6.5, 0 alkalinity, low chlorine. The pool only holds 1,600 gallons (not a typo- very small pool or oversized spa). Recommendation was to drain the pool and start over with municipal water rather than multiple expensive chemicals. The tech also suggested buying shock that does not have conditioner in it as an additive, so I bought their product, “Spa oxidizing shock,” potassium peroxymonosulfate; use 2oz./week). Does this make sense? Thank you!

Welcome to TFP.
If you can safely drain and refill your pool then do it before you get any copper staining.

Don’t buy anything from the pool store or trust any of their tests. Return the MPS and get one of your own test kits (the TF-100 or Taylor K2006C). I’d find it hard to believe the 0 alkalinity, but I might believe the copper test is high if you’ve been using the xtrablue stuff.
An alkalinity of 0 makes the pH about the titration end point I think it's about 4.5 without looking it up.

The Pool Store is reporting an Adjusted Alkalinity.
Pool store TA tests often report lower then what you get when testing with the TF-100 or Taylor K-2006 TA tests. They subtract about .35 x CYA from the measured TA to get your adjusted TA.
With a reported CYA of 158 the TA is really 50-60 which is fine for the pH.

The pool needs to be drained for the high copper and CYA and start over with fresh water and and TFP methods. No reason to waste chemicals in that water trying to fix anything if it can be drained ASAP.
