Any requirements for softened water?

prh129, just be aware that you will only be testing calcium harness, not total (calcium and magnesium) hardness. Total hardness is a different test. Taylor makes a few and most of the pool test strips I have seen test total and not calcium hardness although they do not have much accuracy. As for testing for Iron, once again you will need a separate test for that since it is not in Ben's kit.
Also, my understanding is that when Iron gets trapped in the resin it reduces the efficiency of the resin at removing hardness. When my system was installed I did not have an iron problem and my installer told me I was lucky because he said my resin would last much longer.
