Thats what I wanted to hear. Thanks!

I used it to reseal my tank... no issues up and running two years now

Why would anyone even think of using something that COULD cause potential problems. Just use what the tank builders are using and never think about it again.

I'll have to agree
A few 20s is money well spent to save the whole tank

Maybe Rick got lucky and bought some of the old silicone before they switched it over to the new mold and mildew stuff

We just suffered some minor losses after resealing an old 20g with GE 1, used it in the past just fine. Over two days it damaged some soft corals and killed a small wrasse. CUC seemed fine so I threw the into a larger system.

What can I now do with the rock remaining? Can this be rinsed off in a saltwater bucket and thrown into the sump on our larger system or will the rock absorb the chemicals and release them again? Almost leaning towards bleaching the rock and starting over to be safe.

Toss it :surprise:
The mold inhibitors in the silicone you used are going to permeate everything

Chuck the rock, and everything involved

We've muratic acid bathed rock and bleach bathed before - shouldn't this take care of the chemicals?

That I don't know about as I don't know what their inhibitors are made from. Muriatic eats metals and won't touch anything organic

Maybe someone at GE could let you know what you need to neutralize their chems

Interesting, SCS1200 label says specifically "not for use below water."

It's a liability thing
