I don't think it is safe. I personally would only use silicone that specifically says "aquarium safe". The aquarium safe silicon may be a bit more expensive, but better safe then sorry.

It's fine, they just say that to cover their own butts, as long as it's 100% silicone with no mold/mildew additives you're good.

GE silicone I is fine to use; avoid the one that is for kitchen and bathrooms (GE silicone II)

I've used GE silicone I several times before and never had a problem with it. As said above, avoid anything with anti-molding/mildew and make sure you don't grab silicone II by accident.

It's been used time and time again in the hobby for years. The manufacturer puts all that mumbo jumbo on the label to cover themselves. It's the most widely and affordable large tube of silicone you can buy that works in fish tanks. I purchase it 9/10. Only time I don't is when I need to get into tighter spaces in which I use Petco's small silicone tubes at 11 bucks a pop.

I think it's the window and door variety that you want (GE Silicone I Window & Door)

I've used it several times, but I always check the label pretty thoroughly whenever I buy one.

As said above, avoid anything with mildew/mold/microbial resistance. The stuff I use almost always has a bit on there about being safe for food contact surfaces.

The GE silicone has multiple packaging (window, door, kitchen/bath) but it's all the same silicone. It's probably packaged that way so that it will be placed in each of the separate departments in the store.

Read the label. If it says it has a mold/mildew preventer like most of them then its no good.

I'm not into the image, but into the hobby...

It may be similar but it's not always the same. Shear strength, skin time etc are/may be different between the different types.
While you can use the GE1 for a reseal I personally wouldn't trust to hold a largish tank together as the adhesive. For that use the right silicone. RTV type. There is a definite difference between the shear strengths,

Dilution is the solution for the pollution.
Quote me as saying I was misquoted.
Once you get rid of integrity the rest is a piece of cake.
Here's to our wives and sweethearts - may they never meet.
If you agreed with me we'd both be right.

Not sure what the difference is between GE I and GE II but I've used both (for frogs) and I always used the DOORS AND WINDOWS because it has no mildew resist thingy in it..

The bath and kitchen has mildew resist...

you want 100% Silicone, nothing added...

"Aquarium safe" labels is pure marketing for selling something 3 times the normal price...

A lot of this depends on quantity needed and application.
"IF" I was building a tank I'd def shop around for "recommended" products..
Like this (btw: shipping will prob kill it)

ASI Aquarium Sealant, CLEAR, 10.2 oz

$5.65 a tube certainly isn't unreasonable..

Aquarium Silicone Sealant - American Sealants, Inc.

normally about $10 a tube..

eek bay 5 for $39.. free shipping..
