NP pellets and bleaching events

[whatcaneyedo]

I had the same issue while using the vertex pellets. I tried them twice and the same thing happened each time. The first time I used the recommended minimum amount and nearly all of my soft coral plus a few of my LPS began to bleach within a month. The second time I used much less and the same thing happened. I don't know if it was related or not but my montipora also bleached and receded a bit a few months after trying the pellets. While it seems unlikely that they would cause that months after their use I can't come up with a better explanation. My oldest montipora I got back in 2005 and the only time I've ever had any problems with them was when I tried pellets.
