I have just two rocks that have coraline because it comes from the pet shop, but the rest of my rocks are covered with a brown-green algae and very few coraline. The others rocks are very yungs because it comes directly from the sea and I decide to kill it for my benefit. I will use purple up with stremly careful and will searching for the test of calcium. I had the test of alkalinity, just I don't know it measurment.
