aquacheck 5 test strips indicate my free chlorine is 10 ppm (purple color on test strip) while total chlorine is around 2 ppm (pale green). How can this be? Seems like free would always be lower than total.
thanks
Free chlorine higher than total chlorine?

Your opinion is correct, Total chlorine (TC) must equal free chlorine (FC) plus combined chlorine (CC). One reason many people ultimately abandon test strips.
There are two test kits generally thought to be good from the homeowner - the Taylor K-2006 and the TFTestKits TF-100

Dump the strips. Get the Taylor K-2006 test kit.
