Losing Corals fast...question about GE Silicone II

I'd say that if the tank is fine now, it should stay fine. I don't think chemicals hang around for a while and decide one day to leach (relative to this scenario).
As I mentioned, I used the GE II and had no problems, so I wouldn't now tear my tank apart to replace it
Based on the rep stating that the formula changes, I probably wouldn't use it again, just in case. Silicone I and GE 1200 are both safe options, so I'll use those on future tanks.

I think you are right again. If you are not having any problems now, I doubt you'll have them later.

Aquattro, you mentioned that GE I and 1200 are reef safe. Do you know where I could buy some?

Finally, do you guys think that it's safe to use the sand that's currently in the tank again? It's practically new sand but I am not sure if it would absorb some of the toxic stuff that the silicone has released in the water.

Oh Man, sorry to hear this. One of the few tanks that we have yet to see. What a shame. I to have used this silicone, but have left things for weeks before i used it, with no issues. As for your sand, wash the crap out it and you should be fine. Good luck, and hope things pull through.

I left my rock and sand in after the crash, its fine now. ( over a month) it did take a while to stabalize and things kept dying for quite a while. However you guys are probably right the toxins break down or dissipate over time. Keep the carbon going and change the water lots.

GE I is available at most stores, but generally only in clear, white and brown. Black is tough to find.
GE 1200 is harder to find, although some people have posted places they've seen it. My LFS always carries a few tubes, and I can go to Sea Star aquariums and buy there in a pinch..

thanks I did find some posts saying the GE II (for Bath) was mildew containing , but the GEII (for door and window) -the Blue and white tube was ok from what i read may not have the mildew inhibiter.
However it still crashed my system.
Regardless, I am really sorry for your tank situation total know how it feels.
Thanks for the advice on leaving my sump in place now . Wouldnt want to do that job again.
