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

I used this to determine the calcium level in my tap water so I can use it for plants. I need to know the levels in order to adjust my nutrient levels accordingly. The test was easy to use and accurate. I tested my tap water and compared it to rainwater that had 100ppm calcium nitrate added. My purified water readings were exactly what I expected. I just received iron test strips from another company and they didn't work at all. So I was worried but this test works great. 5 Stars.
