Is this the right silcone to use to reseal a tank?

Read a few post and came up with GE(I) as being what most use so I picked some up from home depot the tube I got looks different then the other pictures of it I have seen the stuff I got is 100% silcone. So did I get the right stuff?

You should probably read the sticky about the DIY 75g tank; the author mentions having a hardware store grade sealant blow out a pane and suggests using a high strength version available locally in many cases. ("RTV108")

For how little you really need just buy the stuff that actually says for aquarium use. What is the price difference if you calculate how much you'll wind up throwing away anyway? (Rhetorical, answer is: Not much)

No GE I silicone says safe for aquarium use. They don't guarantee it for that purpose and by putting that on, it absolves them from any liability if you use it for that use and your tank breaks and floods your house. It is fine though and 100% silicone is 100% silicone and any 100% silicone from the LFS is the same thing, just 10x the price.

So after spending half the night reading 100's of post online about resealing tanks and the types of silcones to use I found that most said the GE I and other silcones like it are fine for tanks up to around 30g, 50g is pushing it and 75g you would have to use so much it would have been a nightmare so I took a 3 hour raod trip to Grianger in mobile,al and got GE RTV 108 I might not of had to but I will sleep better knowing I did.

Personally, that's the way I see it too - you went to many hours of trouble to clean off that glass, you might as well do it right. At least you'll be able to go to sleep without waking up at every little sound thinking your tank just popped.

People have been using that exact product on aquariums for decades. You don't want GE II, and you don't want the stuff that has a mold inhibitor.

(Some people have successfully used GE II, but it leaches ammonia for a long time, so I wouldn't try it. It's much safer and easier just to use plain old GE I.)

Never argue with a fool. Onlookers often can't tell the difference.
Growing older is mandatory, growing up is optional.
My advice is free and worth every penny.
