Did you neutralize the chlorine before running the lab test? Though, high chlorine usually makes pH look high.

Is Taylor still using the self-neutralizing phenol reagent, or is it the non-neutralizing agent? If your chlorine levels are high try adding a drop of the neutralizer to the Taylor test--I THINK it's bottle #7 and see if the results are more consistent.

Also, this is a rare case where I'd double check with either a Hach or LaMotte brand test strip and see which it confirms...if you have the strips around.
