How many total gallons is your system? I am on day #3 and I have seen no adverse effects. I do not have any ill or stressed corals but I am going to monitor growth and color differences. I am using the generic Walgreen's brand with rose hips. Have you given any thought about adding some of the"B" vitamins as well?
