Silicon..

Hi all,

I buildt a cave from ceramic slates for my catfish, gluing the pieces
together with silicon. I used casco transparent glass silicon, it has the
number 2985 on it. It says on the tube it's meant for aquariums.

However, I'm a bit concerned becuase now after 24 hours I can still smell
the silicon, a rather unpleasant odour. I'm reluctant to put my piece of art
into the fishtank becuase of this smell :P Have I used a potentially
dangerous silicon? should I wait longer than the 24 hours it says on the
package?

It'll be ok, you wont' smell it when it's underwater.. hahaha... jk...

but seriously, leaving it out for 24-48hrs to 'cure' is recommended. After
that, you can rinse it off and throw it on in the aquarium and it'll be
fine. realize that thicker portions of the silicone may take longer to
cure... but the smell will be there for months if you wanted to wait for it
to leave... it's ok to put in the tank after it's cured.

Hmm, I don't know if I would throw it in right away. I've never smelled the
silicone in aquariums, so the smell does go away pretty quickly (unless all
the aquariums that are sold are put in storage for months until the smell
goes away). I'd give it a couple more days to cure, especially if you used
thick patches of glue. Then if it still smells maybe soak it in water for a
few more days changing the water daily.

I got that line, but I was simply recommending a somewhat more cautions
method (ie: if it still smells after 48 hours, leave it for another 48, or
maybe 96, then if it still smells, let it soak in water, not just wash). I
didn't mean to come across rude in any way, form, or shape.

When I've used silicon for aquarium projects, I've generally had to
wait several days for the smell to fade. Heck, the new ten gallon tank
I bought this weekend smells very strongly yet. Fresh off the assembly
line, I guess.

Give it some more time, it will clear up.

Thank you all for your replies. I'll give it a day or two more to cure. I
don't want to risk my Zebras getting poisened!

Thanks again.

Just give it an extra 24 hours... really depends on how thick you
applied the silicone. If you can smell it, then it has not finished
curing yet and should not be placed into your tank as it _may_ poison
the fish.

That's fine, normal silicon contains a mould resistant agent that will kill
any bacteria and therefore is not suitable for fishtanks, but people have
gotten away with making tankt from them for years though.


However, I'm a bit concerned becuase now after 24 hours I can still smell

Depending on the thickness of the silicon it can take days even weeks for
the silicon to fully harden but normally it should be just fine after 24-48
hours.

The smell that comes from true silicon os actually acetic acid (CH3COOH, pKa
= 4.76) and could potentially lower the pH in your tank but for the small
amounts normally used I wouldnt worry to much...


The smell can take a few weeks to go away depending on the thickness of the
silicon applied and temperature, I usually wait 3-5 days after I do silicon
woak on my tanks before putting the fish / water back in just to be on the
safe side.
