So, tonight I've decided to temporarily suspend use of NPX-Xtra pellets on my tank.
The nitrate is down, the phosphate is down, that part is great. But what has me puzzled and a little troubled is the bleaching now going on in my tank among the two carpets, my green bubble coral, and the acan's. It all started roughly two weeks ago and has been getting steadily more noticeable every day. The coincidence in timing with the pellets is unfortunately very difficult to ignore.
The one thing that might set my tank apart from others is the fact that I dosed kalk at night to maintain Ca/Alk levels, so I have to wonder if it could be interference with the kalk that could be the issue.
So for now I've turned off the pellets and turned off the kalk as well just to see if I can reverse that trend. My two gigantea carpets are more important to me than the PO4/NO3 numbers so I'm really hoping that this can be fixed.
