I tried my first calcium test last. I bought an Aquarium Pharmecueticals calcium kit from LFS
. The kit works like this: Add 10 drops of solution #1 and shake for 10 seconds. Then, add solution #2 one drop at a time and shake 10 seconds and the color should change from pink to purple and finally to the end color which is a deep royal blue color. You count the number of drops of solution #2 you've added and read the calcium in ppm
off of a chart. According to the chart you should reach end color condition after about 8 to 12 drops of solution #2. My problem is I could never reach the purple or blue end color. I added 20 drops of #2 and it pretty much stayed pink. I tried the test twice - same results. I followed the test kit instructions to the tee.
Just wondering, is my calcium wildly off the charts? Do I have a defective test kit? Am I doing something wrong.
