Hey all,
I currently use Red Sea test kits for Calcium, Alk, and Magnesium and I was contemplating switching to hannah checkers but I wasn't sure how well or accurate they are for calcium and alk. I'd love for some people to chime in on how they are for those two tests. I keep an SPS reef so having good test kits is pretty important. Sometimes the color changes on the Red Sea test kits can be questionable so it's hard to tell exactly at which color change is where my level is.
