thanks christy, should i "wait and see" in the next couple days if this RTN will continue to spread on the larger birdsnest colony? or should i frag as much as i can? Id try to cut out of dead zone but its right on the base/in the middle of everything so itd be a pain in the a**.

Yeah birdsnests are a pain that way, I'd just leave the main colony intact, maybe frag a large piece off if you can. Its hard to say how crabby it is about the whole thing and whether the tissue necrosis will continue or whether it will just stay as it is. Its kind of a crap shoot really. If you're totally in love with it, frag a chunk off but if you can get another piece or are indifferent, just wait and see

Provided your test kit and testing habits are accurate stripping the water of 0.06 ppm of phosphate isn't enough to cause that sort of reaction. Now, if you had 1 ppm and stripped it down to 0.08 ppm or something like that, then maybe you would be havin some issues. I think something else caused your RTN.

Personally I use pellets and GFO. Bacteria utilize NO3 and PO4 in a certain ratio. The bacteria can sometimes become nitrate limited meaning it will consume all the nitrate while there is still phosphate left over.

I was thinking about trying that in the future. The only other thing i can think i did recently was bring salinity down from 1.028 to 1.026 during a w/c. Unfortunately i did this and added GFO during the same week maybe it was a combination it didnt like.

Going down in salinity by two points won't harm the critters either. Going up is trickier. If the salinity was at 1.028 for awhile that could have been the cause of the RTN. How are you checking salinity?

Vertex Refractometer. I didnt calibrate it for a month and it shifted my reading by 0.002 which is why i did a salinity shift.
