I have an original PoolForum test kit (roughly the "original" to the TF test kit that we all know and love). Since the hardware has been fine through the years I just order the refill set from Duraleigh.
Im not sure but I thought I heard along the way the CYA reagent in the refill kit isnt calibrated to the original test tube...is that true? Just want to make sure my tests are accurate, and if not is there a way to convert current to old. The view tube I have is marked Taylor with red lines and numbering.
Thanks in advance.
