I have a large peice of frogspawn that I have had for over a year. it has always doon very well. It is now loosing its color. It was a nice pink and has turned to a very pale pink. I also have a trumpet coral that is doing the same thing. My water parameter are all fine. I have been treating my tank with No-Ich Marine. It is reef safe and came highly recommended because it does not harm inverts. Could the medication be the cause or is there something else going on.
