I have lots of Xenia, pulsing and have a tank this is near the end of cycling after changing the pump, sump and move the refugium to another area.

I move a piece of Xenia to the tank with high, mildly high NH3 and it bleached the entire piece, moved it back to the original tank, still bleached and pulsing as of this afternoon.

Anyone have experience in this area ?
