New Sump BIG PROBLEMS!! HELP

[yellowworld]

Hey guys, I have a 90 gallon tank witch just had a glass box under it before, i had yet to put my baffle into it, it is cycled and i finally got around to it last weekend. I got it all together and running right, but i noticed my water was looking a little cloudy. I thought first off it might be the extra water i added to the system so i added two massive bags of carbon and waited but it didn't help, I now tried a 25% water change and that hasn't helped out either. Now im thinking it has something to do with the type of silicone i used. I have used it before on numerous set ups with out any problems, how ever they were much smaller.

I used this stuff right here http://www.plumbersurplus.com/Prod/G...t/274?RefID=CJ

dose anyone have any thoughts that can help me out? My corals are looking very sad and right now i'm adding bacterboost, and a stress reducer to keep them a bit happier.
