My tank has been up for about 10 mths now. I added a GFO reactor about 2 mths ago bc my phosphates were a bit high. I do a 10% water change weekly. I test often and my phosphates, nitrates and nitrites are undetectable. Mg is at 1500, alk 9, ca is 430. Everything was going great until 2 weeks ago. I started to notice tiny oxygen bubbles on the rock and some of the plugs of my coral frags. I also noticed some of my zoas weren't opening up and brown stringy like algae on my toadstool and clam. I did a little research and I believe they are dinos. I covered the tank for 3 days, stopped water changes, and began dosing hydrogen peroxide. All evidence of what I saw before has disappered. I've reduced the photoperiod to 5 hours a day but today I noticed some more oxygen bubbles around my frag plugs. I've noticed through research that a lot of tanks that have been hit with these things have near perfect water chemistry. I know some people say to increase GFO, but I'm wondering if I should remove my reactor completely. Anyone have any ideas?
