I've read over the pool school info, got the TF-100 test kit, and am doing my first tests.
On the calcium test it said put in drops of R-0012 until the water is blue. It doesn't say what shade of blue. It has turned a light blue after 10 drops, which means the calcium is low. My question is if the shade of blue matters.
