Losing Corals fast...question about GE Silicone II

[Aquattro]

However, this was over a year ago, so if the formula changed, you might be affected by it. Last year your buddy was right, GE II "was" reef safe...

I just used GE II about a month ago to build my new sump. I read there was issues when it was not left to cure long enough, I left mine for about 5 days until it didn't give off a smell anymore and have had no problems with it. There are two different types, one with mildew inhibitor and one without, I was told to make sure that I used the one without. Are you sure you used the one without the mildew inhibitors?
