What is MB7?
Odd that you mention it, but I've gotten some birdsnest frags recently (Stylophora, Seriatopora, and Pocillopora) that just wouldn't adjust to my system, and subsequently melted. I just chalked it up to some systemic thang, but I dunno maybe it has something to do with the pellets.

I know this was mentioned quite a while ago, but I too had birdsnest die after running the pellets. Both a pink variety, and tubbs, slowly began to get a lack of polyp extension followed by stn. I do not know if this is only limited to birdsnest as I have lost all of my sps within the past few months. I am not blaming my loss solely on the pellets because I was already having poor polyp extension prior to running the pellets.
Sorry to hear about your sps's.
I have not been able to keep any birdsnest for a few months now either. Mine stn'd way before adding the pellets. I did buy a small frag of the tubbs and it has not rtn'd but it doesn't look great. All my other monti's, pocillopora's, millie's and acro's are doing great.
What happened to your tank?
All of my sps began to stn, I think it was due to all the changes ive put the tank through the past few months. Im now sps free, and intend to keep it that way for a month or so in case the culprit was some kind of pest. I also plan on keeping my alk around 8 dkh as opposed to 10, as ive heard higher alk can have detrimental effects on a tank when using pellets.

I can say from my experience running half liter on my 120 gallon reef that when my alk got to 11.2 dkh that my Duncan wouldn't open, my Blastamossa lost a polyp and one of my Acros wasn't extending his polyps. I was running my calcium reactor hard thinking more is better.
When I took my calcium reactor off line and allowed the dkh to go to eight everything is recovering nicely and looks better. I am now running my reactor more conservatively.
Myself personally I will never run my system with a high dkh and run bio pellets. I feel we really don't know the full affects of running a ultra low nutrient system. Better to try to keep everything close to Seawater when running ULNS.

OK, I added my other 500mL of pellets. I tested my water and these are my parameters:
SG - 1.025
Nitrates - 80+ API
50 - Salifert (new)
Phospahtes - 0.5
MG - 1170
CA - 480
dKH - 13.4
I had a slight bloom this first week with the first 500mL. I will expect a slight bloom this week with the second 500mL. Other than that the few corals I have seem to be fine and the fish are fine. Water does seem to a bit clearer but that is just my preception - no proof :spin3:
Salty, How about an update. My system is similar to yours
