Default New GE Silicone I opinions??
GE has new packaging for Silicone I tubes that states not for use in aquariums. It still states 100% silicone as previous. The small squeeze tubes look the same as they have for years and don't reference aquariums in the instructions.

Any news on this product still being reef safe?

I'm pretty sure even the old stuff said not for aquarium use lol. Probably just a disclaimer to avoid liability.
Home hardware carries a product which is quite inexpensive 10$ for 3 tubes and says in large letters safe for aquarium.

Apperantly GE has changed the formula and all GE silicone except for the SCS1200 has a small portion of the mold inhibitor in it & should not be used in aquariums.

Good. People shouldn't be using sealant for tanks anyway. It is an extra $3 to get the scs 1200 adhesive rather than the ge1 sealant.

The SCS1200 is actually very reasonable, I bought a case of 24 at Sabic PolymereShapes for around $125.

Wow, that's good to know. I've been using the GE Silicone I Doors & Windows for years in my sumps. I don't think I've had any issues...

Usually, unless the silicone is re-packaged like All Glass stuff, etc., the packaging will say not for aquarium use. Water will break down silicone over time (technically) so it's totally a liability thing.

I got it for pretty cheap at Calgary Fasteners.

Fair enough. Do any big box stores carry the SCS1200? I'm sure I've seen it at the LFSs but it was nearly $20.

The old packaging says "not for aquarium use" as well. I think that's for liability.
