So, I started the pellets on friday, I got them to tumble very nicely in the way described above by others. I have checked all the parameters and no change yet. I know it takes awhile for the pellets to take affect. The reason I tested the water and tested for everything is because saturday morning when the lights came on my tank was a nightmare. Both my Green Stylo and Purple Stylo were dying. They are now completely dead even though I fragged what I could and put them in another tank. Since then I lost half of my ponape as well. Everything else looks ok for now. Looked in the tank with a flashlight this morning and the rest of the SPS looks ok. The only change made to my system was the pellets. I read on another site that some people also lost a few corals when they started pellets. Now I wish I would have not gone with them.
