SPS 911

[daniella3d]

well..nitrates of 10 is pretty high for SPS.

What about calcium? magnesium? what other corals in there? chimical war? fish ?? parasites? If they all do this, then it is clear that there is something in your tank, either water parameter (copper?) or something attacking them.

Do they shed skin fast or slowly and starting from the base?
