Correct pH before relying on an ORP reading: high pH reduces chlorine effectiveness and makes ORP read low even when a test kit shows adequate free chlorine. High stabiliser and high salt levels also lower measured ORP.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Regular manual water testing is still required, even with pH and ORP automation installed.
