Hi, opened pool 4 days ago, using three year old TF100 test kit, all levels where they should be except free chlorine
I followed same routine and amounts added at start up as past few years to get it going
CYA - 65 (from 3 gals added)
salt-3200 (from 8 bags)
FC-0 after 3 gallons
Usually 3 gals liquid chlorine does me just fine, cant get any reading though, I can smell the chlorine in the water also
water is crystal clear and clean.
I'm now wondering if the 870 DPD grey powder is old now and not working??? Three year old TF100 kit.
any suggestions appreciated
