Review on 🧪 Salifert Calcium (Ca) Test Kit - 50-100 Testing Range by Jessica Morris

Excellent, like most Salifert reviews in my experience (don't remember trying their copper; for that I use the Hanna High Range Kit that comes with salt water works ). Accuracy testing multiple sets from Reef2reef.com article. I've read that someone has tested various kits against the Triton standard, accurate and the endpoints are easy to pinpoint so it seems very reliable and trustworthy (unlike Elos which also works well with slightly less precision, but the endpoint is harder to see with the eyes). Pretty easy, just 1 extra step away from Elos. I also only use Salifert for alkalinity and magnesium.
