GE Silicone 2

[cncreef]

I have building a system and discovered that I used some GE silicone 2 along with other tubes of Aquarium safe silicone.

The system has been without any water yet and has been curing for 2 years, since it is cured will the system be safe to use?

the total water capacity is about 300 gallons total.

opinions?

As long as the GE didnt have mold or mildew inhibitors

well for GE-II I think 9.8fl-oz (GE5000) MSDS says its got stuff like this in it. It also says don't use it on aquariums. I not sure what those are for sure without doing more research.

Distillates (petroleum), hydrotreated middle
Silanamine, 1,1,1-trimethyl-N-(trimethylsilyl)-
Tin, dibutylbis(2,4-pentanedionato-.kappa.O2,.kappa.O4)-, (OC-6-11)-

If memory serves the GE I says not to use on aquariums as well. I suspect that once fully cured either will be fine. GE I is an acetyl cure silicone and stinks; GE II is a neutral cure so don't assume lack of strong smell means it's cured.

i dont think length of cure has anything to do with it as its designed to kill mold for many years...and GE I and GE II for construction use have those additives...i'd razor it out and cover with the real stuff

Just go to your local fish store and pay the $10

I used GE II on my sump cured 7 days with no problems. Just make sure there are no mold inhibitors and that it is 100% silicone. GE I is no good because it has that stuff...but if you want to be safe, go with the stuff that is meant for fish tanks.

GE II Not reef safe.
GE I Reef safe, harder to find, and it says do not use in aquariums.
