The first year, I took a baseline measurement of my tap water's hardness and it didn't even register on the strips. Every 4 months, I would retest, and even the last one barely colored the next color on the test strip. I guess this is how i forgot about changing them.
Anyways, I put in new ones and set a reminder on my calendar for once a year changing.
Should I be concerned about scaling of my boilers or anything else?
