I have been using bio pellets for about a week now, but there is a
HUGE change in my tank. 1/3 of my frag corals when I first bought in the LPS store were all brown, but now they have all changed to their true color. I was testing my phosphate and nitrate, they are too high even I had just changed the water before I set up the reactor. I have bought a few new sps frags today, so I decided to test the water again, and to my surprise the phosphate was undetectable, nitrate was 0.5 
I used to have to clean my glass every morning before I go to work, but now only twice in this week and it was very little to be concerned about. The hair algae were half gone, same with brown algae. I only used 25% bio pellets, not even going to the full amount yet. All I can say is WOW !
