NP pellets and bleaching events

[Casey8]

I was using Vertex bio pellets for about 6 months. I lost more than 2/3 of my sps corals, thay were bleaching so fast that I couldn't save any frag from all my colonies. I didn't have any clue why my corals got bleached untill I decided to shut down those pellets, whatever sps corals I have left, they had turned back to their true color in just a couple weeks. Big lesson, I won't use them anymore in the future to control nitrate. I'd rather do water change more often.
