You can try underwater epoxy for gluing rocks, PVC, etc... This stuff cures underwater as well as dry, is completely non toxic and will permanently hold pourus material. Here is a link.

Just as an FYI...

I spoke to Tom at GlassCages.com and he said that they DO sell 10.4oz tubes of aquarium silicone, though it is not listed on their web site. Price is $6.00 each. All you have to do is pay shipping (varies, depending on where you live). I ordered 4 tubes today to secure my foam background (when I get it finished) and to have some extra in case I need it. IMO, it is worthwhile because I KNOW this is the correct stuff and the price premium is only about $1-2.

Tell him I sent you.

Thanks.

Scott

PS. I have no financial interest in GlassCages.com and I am not receiving any type of compensation for this. I DID buy a 115g tank from them about three weeks ago.

A lot of questions in this post, Yet they all seem to revolve around a common thread. What type of silicon to use in a aquarium. Obviously, anyone that is list for aquriums will work. They are expensive compared to other ones though. Stay away from kitchen/bath, they have a fungisided to kill molds, and mildew. I use the least expensive 100% clear silcon I can find. This must cure for at least 48, before having water put in the tank, I also rinse the joints first, with water, then drain, and let dry over night. I have never had a lost fish from this method. If you are building the tank, and not just repairing a leaky one, it is more in how the joint is filled with the silcon then with anything else.

Silicon alternative for rock construction

Postby stan buckalew » Wed May 12, 2004 5:49 pm

Ever tried gluing rocks together with silicon? I have. It sucked. Not to be confused with stuck, which it didn't.

Alas, there is another choice.

There is a foam product similar to that used to fill/insulate cavities in walls etc that you can find in the water garden section of most builder supply stores like Lowe's or Home Depot. It is primarily designed for pond water fall construction, comes in black, and is listed as fish safe. Costs about $14 a can, American.

I've tested it and it holds well.[/i]

100% silicon=Silicon I

Postby stan buckalew » Thu Jun 03, 2004 7:58 pm

The brand that is definitely 100% silicon is called Silicon I and is made by G.E. (?) and is currently available at my local Wal-Mart.

The issue withsilicon is not to buy any that say "mold/mildew resistant" as these have an inhibitor in them made from slow release arsenic! At least, that's what I've been told.

I would assume any 100% silicon is safe, with the above exception.

from GE about GE I:

Our consumer grade (this means they would be found at Home Depot or a local hardware store) offset to these industrial grade products is GE012A (Window and Door Silicone I).

not to harrass you mars23, but do you work for GE, just out of curiosity?

not at all...I work in a hospital...and never worked for them. Just something they sent me long time ago and figured i'd post it. GE II has better all round (plastics, rock...etc.) adhesive properties than GE I. Although GE I and II rate glass binding at 7, GE I holds glass better (and this is not GE telling me this, I discovered this myself along with many others. Both can be used, you just need to get the windows and doors (blue tube) and not bath and kitchen (red tube, has mildew prevention, fungicides..etc.). The one difference between GE I and II besides binding properties is the way they cure. GE I cures via acetic acid and GE II via ammonia. I just figeured I'd post this stuff to clear the confusion I thought everyone had known. The disclaimer about not for aquariums is, from what i had known to be circulating (not sure of the truthfulness about it though) is that GE was sued when a big aquarium fell apart and lots of water damage...etc. to this persons house. Now the questions remains whether this person applied the silcone properly and allowed it to cure properly before water was added. I know i leave it for at least a week. From what i've heard (again not sure of its validity) is that AGA uses GE I and the disclaimer previosly mentioned seems to point that without naming AGA. Take all this for whats its worth...just additional information. I've always used GE I without problems and many advanced reefers use it to. Hope this clears it up.

Technically, the "100% sillicon" is misleading. They are not "100% sillicone" if arsenic is added to prevent mildew and fungus. However, it is my personal belief that the amounts of arsenic would be very insignificant. There is arsenic in normal tap water, just in very small amounts. However, I still wouldn't use it myself.

Does anyone know if the tube of GE I sillicon claims to be food safe?

I think the best would be something food safe and aquarium safe... I don't know about that DAP product...
