Troubleshooting:

ISSUE	POSSIBLE CAUSE	RESULT	CORRECTIVE ACTION
Test results appear different with new strips	Lot Code for test strip(s) was not updated with new bottle	Test results may be inconsistent/unusual	Update test strip lot code in Xpress Flex sureTREAT program.
Total Alkalinity (TA) seems low	“Adjusting TA for CYA” is turned on in sureTREAT	TA is reported lower than a titration or other test	Retest with “Adjusting TA for CYA” turned off. Note: “Corrected TA” is what a proper balance (LSI) requires.
pH result is unusual	Sample could have low Total Alkalinity	pH is inconsistent or different than another test	Increase alkalinity of pool/spa and return for a retest.
Hardness result seems high	Test Strips report Total Hardness rather than Calcium Hardness	Total Hardness may be higher than Calcium Hardness	To determine a more accurate result for Calcium Hardness, a titration may be required.
No test result for CYA test	CYA pad on Flex 3 did not reach sample during dipping	CYA reading will be inaccurate	Retest with fresh sample and proper technique to ensure pad reaches sample.
No test result for CYA test	pH is outside the range of 6.8 to 8.2	No CYA result is provided	Adjust pH of pool/spa and return for a retest.
Iron test result is lower than expected	No prep reagent added to chamber 1	Iron test gives repeated <0.15 ppm result	Retest with fresh sample and use 1 scoop of Iron Prep Reagent (R-9103).
Report Quality - Report is excessively long	Text in recommendations section could be excessive	Report for customer is more pages than desired	Edit recommendations in the sureTREAT program.
