You need to get rid of your combined chlorine and there are 2 ways to do that - either bring your free chlorine to 7 to 10 times your combined chlorine level or throw in the correct amount of non-chlorine shock - your combined chlorine should be 0.
Your CYA (cyanuric acid) is awfully high for only 2 weeks worth of use - I don't know if I would believe that but if it's true some manufacturers say to dump the water when the CYA is about 100.
Some people believe in hardness some don't - if you do, get your hardness up to the recommended amount. Alkalinity is another matter, if your having problems with PH fluctuating a lot then you need to get your alkalinity in line - it helps "lock in" the PH (it still fluctuates but not as much).
I don't know too much about Copper and Iron but from what I've read they could cause problems if their too high (what that is I couldn't tell you). They do sell "metal out" in stores.
Get away from the test strips and buy a Taylor K2005 kit. Not only is the kit accurate, it also comes with a water care booklet. The kit will test for everything you need except metals.
Good Luck!
