I don't know what it is about SW tanks sometimes. About two months ago my tank looked the best that it ever had, I had started zeo and everything was showing growth and colour and I could not have been happier.

In the past month however everything has gone down the tube. I have been fighting a losing battle with cyano, it just will not go away and just keeps getting worse not matter what steps I take to stop it. My SPS are browing out and even starting the first stages of STN.
