I recently bought a used 55 gallon tank, "leak free" they said, off of Craigslist. After gently transporting it home and filling to check it, I could have used it for a lawn sprinkler. I completely broke it down, cleaned it, and reassembled using the silicone II from G.E..... Perfection. (Or I hope so, as it's sitting on a 100 yr. old heart pine floor!)

THE KEY, to ANY assembly/reassembly, before consideration of whatever you decide to use to stick it together with, is preparation and cleaning!!!. A mere misplaced oily fingerprint can spell disaster.

Do not use the GE Silicone II Kitchen and Bath I used it to reseal my tank let it sit for 5 days then put my fish in they got sick and the silicone was peeling off. then I got Dow Corning 732 now that some good stuff.
I've used pretty much all caulking of any type ~silicone,acrylic,urethane, etc~ in 30 years of construction. I've found NOTHING wrong with the G.E. silicone II in tank construction. AGAIN, it's all in the PREP AND CLEANING. If you don't do it properly, ANY sealer can fail. period. My oscars showed NO ill effects from using the silicone II.

Since tank manufacturers use the acetic cure version, that is good enough for me. Up here there are a few house brands that state they are "ideal for aquariums" on the label. That is what I normally use, and they are marginally cheaper than the GE. However, if I was building a large tank, I would use the GE 1200 series, for it's extra strength.

Hi, I have been reading all these old posts about silicone, did you ever find something that works and will hold up when cleaning and rearranging the tank?
Hope you're still out there.

ok, so that would be something you would use w/ a caulking gun? and would you need cure time?
Thanks, Anne
The larger size containers need to be used with a caulking gun, but the smaller tubes are like what toothpaste comes in. they're both around $4-5 at HD/Lowes, but you're getting like 11oz vs 4oz. The smaller tubes can be resealed (easier), but I dont know how long it'll keep.

i used ge silicone I kitchen bath plumbing and it killed a bunch of my fish... the guy who made me my 3D backgrounds says he has used it and this didnt happen... apparently ge is putting moldicide in all their silicone products and the west coast has the older tubes without the moldicide and the east coast has it with the moldicides... i however found at home depot a ge silicone that its only name is ge 100% silicone.. its not in the paint/silicone aisle its in the aisle where the plexiglass and acrylic sheets are and it looks like this..



no matter what anyone says that they've used ge silicone I or II *** used both and they both have killed my fish... so this is the no argument alternative... oh and ps does anyone have any suggestions on a good way to get all the silicone residue off the back of the tank? *** scraped as much of it off with a razor as i can but theres a bunch of smudges still on the tank idk if this will kill my fish or what i could use to get it off thats safe to use on the inside of a tank.. any suggestions?

the guy that i met on here that made 4 of my backgrounds that does this for a living.. he makes backgrounds and installs them in peoples tanks called ge and they told him they are putting moldicide in all of their products wether it says it or not. they jus havent phased out all their old stock without it.. *** used the ge silicone II windows and doors and the ge silicone I kitchen bath plumbing and he said he's used the same one i just used and it def killed my fish. if you look anyone thats said they've used any of these products without harm is from the west coast... anyone that says that theyve used the products and the fish died is from the east coast. all i know is the one i just posted doesnt kill anything and isnt even meant for caulking windows, doors, drains, plumbing nothing.. its just 100% silicone nothing else... and it was only $6 a tube.. if you'd like to talk to him hes on here. heres his diy thread of his own tank build hes a real nice guy and he made me some killer backgrounds dirt cheap

The problem is that you didn't use GE I WINDOW & DOOR, Mike. I spoke with GE two weeks ago and was told by the rep that the only version of their silicone that does not have the chemical mold and mildew inhibitor is "GE I Window & Door."

Hate that you lost fish, mate...
