Losing Corals fast...question about GE Silicone II

[toytech]

Wow that sucks , sorry about your corals. I just set up a cube that i re-sealed with black ge silicon 2 and even after compleatly drying out my live rock so i could epoxy it , there was minimal amonnia . I have tried to introduce a couple of sps frags only to have them bleach and rtn though.If ge is really putting extra stuff in there 100 % silicone im p***** how is it 100% if theres other crap in it.
