Hi All,
I have been using Red Sea test kits for some time and find them to be quite user friendly. However, I have recently been doubting the way I read the change in solution for each of the Ca, Mg and Alk test. Please let me know if this sounds correct:
Ca:
Starts with a bright pink color and at a point turns (almost instantly) to a heavy purble-blue or even dark blue : at this point I take my redaing
Mg:
Starts as a bright pink color and at a point turns to dark purple. If you carry on adding titration fluid it will then turn to a dark blue : I take my reading at the first color change (dark purple) - is that wrong?
Alk:
Starts as clear, then turn a very feint blue and at a point turn to a yellow/tan color : at this point I take my reading
I think the way I am doing Ca is correct but not so sure about the Mg and Alk.
Please assist ....
Thanks
