So I have tried a few times testing my calcium and the color never changes from the grayish blue to the deep blue as indicated it should. I have went over the steps a few times and done them byu the book each time, starting with 2ml of tank water.
I can successfully complete the Alk and Mag test, but the CA kit doesn't work as should.
Any advice?
Thanks.
