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.
