Aquarium silicone

Hey guys I just got some specimen containers for free from work and some of them are cracked. I don't mind them being cracked I'm not looking for pristine condition in there as I have a 1 in a half old daughter who get into everything anyways. Bt I was wandering what type of silicone I can use to repair them, without having to buy aquarium silicone. I have tone of bathroom silicone and window sealant etc around. Wat is the ingredient I should watch out for as well. I would just use superglue but I'm around that won't hold up as well.

must....have.....more....moss n shrimp!!!!!!!!!!

They sell one in the silicone department at home depot. It says aquarium safe on it. It's green/yellow package...DAP All-Purpose adhesive Sealant 100% silicone has yellow fish on it.

For about 5 times the price for smaller portion. Just find a gun tube silicone that is 100% silicone with no mildew inhibitors. It's usually the some of the cheapest stuff available.

I would not trust a cracked tank sealed in silicone. Full of water at least. Great vivariums

Patience once drove a man insane

Thanks for your time

There not tanks, there specimen containers, lees to be exact, I'm just using them to store extra plants on my tank I have no room for, or am selling, also I might drill small holes in one of them or make a diy breeder that dumps whatever babies back into the tank. Possibly more for shrimp.

@soothing; I just bought some aquarium sealant today I didn't really want to risk using the acrylic silicone.

I'd have to look at the label to be certain, but I think it's the GE I window & door.

It will say "not for aquarium use", but general consensus seems to be that it's put there for liability reasons.

make sure it doesn't say anything about mildew resistant or anti-microbial, and usually it will have some bit about being safe for food contact surfaces. Also, if you don't have a caulk gun, usually you can buy a cheap one for ~$3 that will work good enough.
