Is says acrilic latex caulk plus silicone
can someone help me out
 
Are you using it on glass? Straight silicone is better than acrylic on glass.

Buy GE1 window/door silicone. That's what you want.
 
Nvm it says it has Ethylene glycol
 
I go through this and have to do research every time I buy some. Thats why last time I needed some I got a bunch to spare me the headache next time. I reccommend you atleast keep the label laying around for reference the next time you need some.
Are you building something or repairing? We always like to see builds!
Oh and hows NoHo these days? I havent been down there in awhile but allways have fun when I do.
 
I have to strongly disagree with using GE windows and doors silicone. GE1 is a sealant, not an adhesive, so it has no tensile strength and will not hold the glass. If you call GE and ask abot that product for aquarium use, they will tell you it is not intended for aquarium use. There is an 800 number on the tube.

Momentive RTV108 or 103 is your best bet. It is FDA approved (does not leech at all), and has the strength to hold lass together. 108 is clear, 103 is black. RTV 108 is rated at 40lbs/sq in.

I purchase here (or wherever you find it):

People are going to use what's convenient and available. I'm just suggesting that if you're talking about holding back water - don't you want to use the best options available? I do.
 
Thanks for the info, Clay! I've used GE I with no problems on small aquariums and terrariums, but I've been leary of using it on anything big. That RTV looks like just the thing I need.

Of course their not going to say use it on aquariums, then when the aquarium fails because the owner didn't put it on right they will get sued!

Also considering ALOT of people have used GE1 for rather large aquariums it must be working. I'm not saying that what you suggested won't work, just that GE1 works also.

i have to agree, i wouldn't put it inbetween panes when constructing a tank, but just for resealing i think its fine. A friend of mines resealed a 150 with ge1 and its been good for at least a year now.
