As mentioned above, Industrial Plastics and Paints carries the black aquarium safe silicone. I would call and find out as I don't see it in their online catalog.

Respectfully,

I picked up the same NuFlex 333 tubes that vicz24 brought to our attention in clear. Big bold "Aquarium" wording right on the tube. I found a supplier in Burnaby "Cascade Aqua-Tech" on Norland Avenue...close to 8-rinks for those familiar. Their price was $5.04 for 300 mL tube and they were very helpful.

Great reference for anyone who needs it. Thanks!

OK so I decided my current sump project needed some baffles relocated simple fix right, not. I started to hear that my preferred brand and product. GE Silicone 1 Window and Door had been changed to include a mildew inhibitor. This down right took me for a loop, so took out a tube that i always have in stock cause you never now right, and wow right there in plain English not to be used below the water line or in an aquarium What! What! What!. No, it cant be true. So I fired off an email to GE. asking them why the warning and have they in fact changed their formula to include a mildew inhibitor and the response came this morning here it is

Hello David:

Thank you for your inquiry. However, GE Sealants are not to be used below the waterline, that would include aquarium tanks. We cannot guarantee adhesion when the product is submerged into water (this also goes for the GE Silicone I Window & Door, despite it not having any mold and mildew inhibitors that we kill your fish).

Please contact GE Sealants with any questions or concerns that you might have.

So now we all know GE Silicone 1 Window and Door. DOES NOT!!! contain a mildew inhibitor or anything else that will kill our wet pets. GE can not fully guarantee adhesion below the water line... I really hope this helps clear any more confusion.

Waking this thread up again...

So is it confirmed the GE silicone I all contain the mold/mildew inhibitor now? Or is the above letter from GE accurate still? I haven't been to a store to see for myself. And the product write-up online isn't definite enough.

Is using silicone free hand (not a caulking gun) more difficult than using a caulking gun? I don't have steady hands and I'm not super strong. I've not even used a caulking gun but I could learn! However, if the silicone in caulking tubes is no longer safe, am i looking at the 300mL toothpaste tube of silicone for application? I have a wee bottle of the home hardware stuff.

 

[Diztrbd1]

I wouldn't chance the G.E. Any more....better safe than sorry. I use the Home Hardware stuff shown in an earlier post

 

[C-kidder]

I did some research before and people are still using #1 without any issues all over the place

I used GE silicone 1 in my shrimp tank to make a rock structure and I have had 0 deaths or any water issues yet.
big caulking gun sized tube and was like $6 way better then the small bottles that are 300 ml's and cost 2x as much.

Here is the pic of the stuff I used. You can grab it at home depot.

GE Silicone I 9.8-oz. Clear Window and Door Caulk-GE012A 24C at The Home Depot

Local TimBr Mart carries a silicone designed for Aquariums. Got a cartoon fish on the label...

AdBond 005.
304mL caulking tube.

Weird warning about not wearing your contacts for three days after handling. And to remove contacts before using. That won't work for me as I'm blind as a bat and my glasses would dangle from my ears if I bend over a tank. So why not just use those blue gloves to keep the stuff off your hands?

Thanks for your respones C-kidder and dizturbd1

 

[Diztrbd1]

Silicone or atleast the stuff I used has a awful vinegar like smell and burns the crap out of your eyes if you do it in a confined space, may have something to do with that. And yes rubber gloves would probably be a solution.
I did a Google search on the adbond, interesting thread here:
GE Silicone Problems.. [Archive] - Canreef Aquatics Bulletin Board
I would really avoid using anything that doesn't clearly state "safe for aquariums", but thats just me.....again I am a better safe than sorry kinda guy lol I unfortunately learned the hard way about the G.E. II

 

[C-kidder]

Good article
Looks like a lot of people use it with success and a few others did not. My thoughts on the matter..... Does something with the salt water chemistry have to do with breaking the silicone down or releasing chemicals into the water? With shrimps they are probably more sensitive then just about anything else and they are THRIVING in the tank that I built a rock feature in. I probably used 3/4 of the 290 ml tube in a 8 gallon tank and they seem to be fine so I don't think that its releasing anything into the water.
"GE silicone 1 is safe for incidental food contact under FDA 21 CFR177.2600 *Rubber articles intended for repeated use" it says on the label of mine. Thats usually a good sign. I think letting it cure properly could be another issue people had.
With that being said its a sealant not an adhesive so if your doing a larger tank I would recommend finding on of the ones that's safe and rated as an adhesive to be safe.

Does any one where to get one that comes in black?

Oceanic corals carries GE scs1200 in clear and black, it's a structural (can be used on large tanks) silicone that I can personally guarantee to be aquarium safe (lots of the custom tank builders use it) and I personally use it for small to large tanks

 

[SeaHorse_Fanatic]

I can vouch for spit.fire as someone who really knows what he's talking about, as I'm sure a lot of other members here can vouch for his expertise too.

 

[xinnypie]

Hello, does anyone know if Oceanic corals is still up and running? I tried googling their store but nothing came up. I am looking for black silicone to reseal my fish tank with. I also sent an email to industrial paint and plastics. Thanks!

* Industrial paint just replied, they said they don't have black as it is not fish/food safe

Very informative thread

 

[VElderton]

Can anyone post where this silicone is available locally - I have checked out Rona & Canadian Tire > they don't carry it.

 

[Geoffrey]

Rona should have it.

This is a very old post. Is the information still good? I wanted to ask before buying, just to be sure.

People have asked several times for aquarium safe silicone.
The silicone that is most readily available at a decent price is GE Silicone I. It is aquarium safe and has been used by aquarists to build and repair aquariums since it was originally released.
Here is a picture of the tube you want . Click the attached picture to see the larger view of it .
