Phosban and Recession

[rude944]

So my prized piece, a large Table Acro Mille, has started to recede after I changed water two weeks ago. When I performed a water change I decided to replace the Phosban in my reactor. I have noticed in the two following weeks that my large Danae bleached and I started witnessing recession. I took the reactor offline in the first week, but noticed yesterday that some of the phos media had become stuck in some filter floss. I removed the floss yesterday when I performed a 30% water change. I also removed all the fish(!!!) as I am trying to reduce bio load and get rid of some far too aggressive fish to keep in a reef. My readings right now are:

Ammonia=0
Nitrite=0
Nitrate=0
PH=8.2
Alk= 2.5
calcium=400
Temp=81
Salinity=1.024

The acro is hanging in there, and half of it's encrusted base is gone. I hope the rest of it stays together, sometimes you just can't catch it and you have to just cut the thing up. This makes me sad. :(
I moved it to a place with a bit more flow (tables like flow) and light.

My question is, has anyone else seen Phosban make problems for them?

Thanks for the feedback... Called Travis and he advised to rinse the phos media as he has seen this happen too. Just an FYI in case this thread dies quickly.

i had a similar instace when i used rowasphos
i had mine in a reactor though so lost next to no 'fines'
I can honestly say, 'only use it in dire need'

I use Phosgard by SeaChem running it 24/7. I haven't seen any negatives and I've been using it this way for almost a year. I use wat less then they suggest, maybe this plays a factor.
