Your chlorine is too low; add the shock.
Do NOT add the other stuff; you don't necessarily need it.
1. Get a cheap local OTO / phenol red kit (yellow / red drops)
2. Read the Best Guess page, linked in my blue signature block.
3. Use whatever chlorine you have to raise your chlorine levels to the DARK yellow level (beyond what the test block shows).
4. Order a K2006, so you can manage high CYA levels with high chlorine (test kit page link in the blue block).
5. If the pH persists high (test it YOURSELF, when the chlorine is 5 ppm or lower) add some of the acid, if you have it (lo n slo)
