What glue to use that is aquarium safe?

HI on one of my tank ornament's some fern has come off, what glue can I use to reattach without affecting the water.
Cheers Barry

 

tank silicone maybe?

 

dont they sell something called aquarium glue?

 

Not sure take it epoxy is no good???

 

I used regular super glue and my fish are fine, just let it dry for a long time

 

LOL, Super Glue in a fish tank !? LOL Maybe it's safe when dried really well, but I think I'd be afraid to use it on objects that go inside my tank. I'd rather use aquarium silicone.

 

super glue does have some crazy stuff in it, but i'm glad it's not affected your fish lilsoccakid.

 

You should go with aquarium silicone.I think it's safe for your fish.

 

I think aquarium silicone or any silicone that is generally used for aquariums would be good. However I also used super glue, can't say it affected the fish.

 

I used it on my bubble wall to keep bubbles from going out of certain parts, and it seems fine, but not planning on doing that again!

It affects me sometimes, if I'm painting and I breathe some in... woah. Once I forgot how to walk down stairs for a few seconds, it's really weird; and if you get it on your skin, you feel very dizzy the next morning like it's gone through your skin Cyanocrylate, nasty stuff.

 

yea, that's what people sniff it for.. that "I just finished a model airplane in 1 sitting" feeling. :

 

hI all! Just a query before I go ahead and make an ornament for my fish tank, I don't want to use any glue that could potentially be toxic to my fish. does anyone know of any waterproof glues that are safe to use in aquariums? thank you

 

superglue works best, just make sure to let it dry completely.

also your profile says you don't know about the nitrogen cycle- its unrelated to glue but you should really know it if you're keeping fish.

 

Here’s some stuff I saw at the store the other day. I’ve never used it. Seachem Flourish Glue Cyanoacrylate Adhesive

 

You can use super glue gel.

hI oh sorry I just clicked on the article and I actually do know what that is, I didn't know you could also call it the nitrogen cycle when I signed up, so I clicked no. thanks anyway

awesome might try that

 

I've just been using superglue, otherwise I have clear aquarium silicon sealant for light DIY projects, like sealing a divider in a 10 gallon tank to keep guppy fry batches apart.

okay superglue it is then, thank you all

 

Make sure it's the gel, even works underwater.

 

Cyanoacrylate is the chemical name for superglue.
It seems to set faster if the parts you are bonding are already damp.

 

Super glue. Regular hot glue. 100% silicone. I'm sure there are a few others.

 

This was highly recommended when I searched and it’s what I have been using, Super Glue ULTRA Gel Control from Loctite Adhesives
but as lc 1958 said, as long as it is Cyanoacrylate it should be fine.

Seems like water helps it setup faster too. If I need to se it I apply where I need it and run it under some water in the sink then put straight into the tank. No problems so far.

 

I have this broken fish tank decoration and I wanted to glue the piece back on. What kinda glue can I use? Can I use this glue?

 

Following. I need know what glue is safe also for tanks. Need to get some ASAP!

 

Anything that is just cryano- whatsit superglue can be used, also aquarium epoxy, and silicone adhesive. Check out the trick with cigarette filters, it's pretty wild.

The super glue I have says it's a cyanoacrylate adhesive. Doesnt say anything else so it should work? The other one I have also just says contains: cyanoacrylate glue.
So would these both work?
I'll also have to check that out!

The word is use cyanoacrylate (that was it! Lol thank you) only, so that's what I've done (I know next to nothing myself, I'm just deep in this adventure myself at the moment and it is all pretty overwhelming ha ha. Good luck! I'm using Sculpey right now for a base, most people say it's ok, that's as daring as I get. I know some people use the gorilla glue that foams as well but that's hard for me so I'll skip it, but it seems maybe dubious- in nano tanks I don't need mysterious leaching, ya know? Don't believe the folks that say to go ahead and use the superglue under water, lies all lies, it disperses and splashed my big Hoh driftwood hideously. Have fun and find gloves if you don't want your thumbs to feel like mine now!

 

BTW, silicone sealant is what they use to put together glass aquariums.

Getting the glue on your fingers is the worst lol! And maybe I'll just wait until I go back to the pet store to buy some aquarium silicone! Lol idk yet I'll figure it out but thank you! I hope things go well for you lol

I'm thinking I may just go to the pet store because they have aquarium silicone sealant but I just havent bought any! Thanks!

I keep telling myself to order a big tube off the internet instead of the tiny one, and TBH emergency repair is what I'd keep it for, it was wobbly and slow curng for glueing rocks, wood etc, and I would prefer to get a hot glue gun (something other people use I have heard, but don't know the official mandate on its suitability, if it has one) to get that fill-in effect- epoxy is terrifyingly permanent and.foam so sloppy, cigarette filter/superglue liquid (it smokes!) is magic but it is too brittle for my heavy pieces- I know it's gel for plants (string is a nightmare for me lol) to rock and driftwood. It is a process, that's for sure. Take your time is my best advice for glue noobs (like me)! There is always a way!

 

Can we see a photo of the decoration?

Super glue (cyanoacrylate) glue is good, but it can disolve some foam and plastics (probably not something that is in the tank, but just so you know). If you use it, try it on a hidden spot before you go putting it on an irreplaceable thing you love.

Silicone is inert in water (at least as far as fish go), which is why it's used for aquarium seals. Get the 100% Silicone stuff in the caulk section of Home Depot or Lowe's. Nothing mildew or mold resistant, just 100% Silicone as the ingredient.

I've heard hot glue works, but I dont know about what kind is good, or if there is something to know about it...

Except for the super glue, you'll want to make sure the decor is clean and dry before you try to glue it, otherwise it will not adhere well.

Yes, that, I expected the usual silicone for home repairs was going to be cheaper than the same thing at an aquarium store (or the tiny tube my husband got me at Walmart not quite grasping what I'd wanted it for- I have never had one bust, but I expect I don't want to be fiddling with a toothpaste tube sized amount if it did, knock on wood- I come from earthquake country and I am never too certain everything is going to stay in one place, lol).

 

Any brand of clear SuperGlue will work, but it is easier to deal with the gel type.

If using epoxy, make sure the two parts are well blended so the glue will cure thoroughly. Allow the epoxy to cure fully.

Silicone takes a while to cure. It releases acetic acid (vinegar) so be sure you allow plenty of time for the adhesive to cure and rinse it off before putting it into your tank.

I had no idea it releases acetic acid, whoa! While I'm being so paranoid about residual cider vinegar on my vinegar eels!

Silicone does release acetic acid during the curing process. Once it is fully cured, however, it will be inert.
