Just as a precaution I'm looking to reseal the 70 gallon tank that I bought. I don't think it needs it... but since its already in the house and I don't feel like mopping up 70 gallons of water from the floors I'd feel a little more secure doing it.

now I've heard of aquarium sealer... but is it flat out called aquarium sealer? Is there a specific brand I should be looking for? A type that you would recommend? How long before it dries, is there anything special I need to do to prep the tank before I seal it?

Can you guys tell that I'm new to this? lol

no one? I'm looking to get the sealant today so any advice before I buy something thats no good would be great

Don't take my word as gold, since I am a newbie too - I'm just surprised no one has responded yet.
It is my understanding that GE1 (GEI) is a good silicone to use. I've read any of the silicones that says 100% silicone is ok - be sure it isn't GE2, which has a mildewcide (sp?) in it. You can get the GE1 at Lowes, Walmart, etc. I'm using it in my tanks to attach 3D backgrounds, and I'll be resealing a 55g tank, too. It costs about $5 a tube where I live. You need a caulk gun to apply it. If your tank is small, get aquarium sealer at your local fish store - I hear it's the same thing, just costs more.
There is a specific process to resealing atank - you can't put new silicone over old. Perhaps a forum seach will bring it up - try, and if you can't find the answers you need, post here again. Good luck!

{shhhhh}

You didn't hear me say this but....

{carefully looks both ways}

GE1 and Aquarium Sealer you will find in the same section are the exact same things. Just branded differently for more $$

But you didn't hear it from me...Remember that.

haha, awesome! I'm going to pick some up today. I watched a pretty good video on youtube showing how to reseal a tank... Looks like my husband has a nice little project to do tonight!

Just make sure to scrape all the old silicone off. I learned the hard way

<--------Has successfully resealed a 140g

I'm not entirely looking forward to the scraping of the tank as its so darn big and awkward lol (edit to add that I'm going to do it anyway lol - just not looking forward to it). How long do you guys recommend I leave the silicone on to dry before adding anything?

 

[Diesel3443]

At the very least 24hrs. I would suggest at least 48-72 though.

Unfortunately, the proper way to reseal an aquarium is pull out all of the old silicone and re-do the entire tank.

Allow minimum 48hrs to cure.
