I don't test much. Mostly LPS in my tank, only SPS are monti caps in green & tan. They grow like the dickens (the montis) so I know there's calcium. I don't dose anything either, use standard IO salt. Fish are healthy, my Maroon clownfish pair have been spawning forever, I have some hair algae, not that concerned, it filters the water... I get the refractometer out to check salinity when I do water changes, that's about it these days. When I did test alk regularly, it was chronically low, according to the test kit. My theory is, if there's even a trace of calcium in the water, the coral will find it & use it. It's a hobby to me, not a fanatic, I'm not doing the fish, coral, rock, clean up crew, inverts any favours by keeping them if a 4 foot enclosure.
