Just ran an ICP test on one of my tanks. Some of my parameters were lower than expected compared to ocean water. K, Cl, Na, C, Co, Fe, I. See results attached. I do water changes every 2 weeks. My other tank has only Co, Fe, I off what is expected. What must I do? Do I need to dose anything? The tank with lower parameters is not doing well when it comes to growing corals hence I ran the test.
