I few months back I had a cyano issue. I think because I started to introduce more fish and more food. I was running carbon/gfo reactor and my nutrients were basically bottoming out. Cyano went out of control. I used chemiclean and did a 48hr treatment followed by two 20% water changes, and wet skimmed the rest of the medication out. Tank looked great and then diatoms...these cleared up in about a week.
I slowly stopped using gfo, and brought my levels up to acceptable levels. If my phosphate was over .1 I did a water change to bring it down. I tried to keep my nitrates at 5-10ppm.
All was well then I started noticing this fuzz starting to form on my frag racks. As well as the tips of some of my SPS getting this dark substance on it. It actually killed my pink birdsnest totally. And I realized my nitrates bottoming out. I am trying to dose brightwell nitrate but I have to dose almost 40ml for it to get up to 5ppm and then it's back down to 1ppm the next morning.
I am not running UV and I am definitely looking into buying a unit but don't want to buy one if not needed.
