I've used both Gorilla Glue and a hot glue gun to repair damaged ornaments.
I've found quite a bit of info on GG being safe and non-toxic when fully cured. Most of the hot glue stuff is anecdotal.
With all the problems I've had, should I consider removing those ornaments and repairing them again using something that is known to be safe?

i would definately consider it till you know of a glue that is for sure safe. there is a marine cement that can cure underwater and it is used in salt water to cement live rock togeather and to cement corals to rock.

I agree with bikeguy. I have no experience using Gorilla Glue, not have I researched its use. What I do know is 100% Siliconeis safe. As well epoxy resins that are rated for marine have worked well for me, such as the Holdfast Epoxy Stick made specifically for aquariums/ponds. Carl

I'm going to go ahead and pull them out of the tank and remove the glue.
I'll get some silicone at the pet store and fix them that way.

I checked at Wal-Mart and the local hardware store - they stock a full line of GE Silicone II, which according to your article contains toxic mold inhibitors. To their credit, they explicitly say on the instructions not to use for aquarium applications. The hardware store also had DAP 100% silicone sealant: However, it TOO says not to use it in an aquarium. So I guess I'm relegated to getting some at the pet store the next time I'm in town.

BTW, can you make your warning about GE Silicone II a bit more prominent? I actually didn't catch it the first time I read it.

Actually the one you posted a picture of is perfectly fine for aquarium use. Dow Corning manufactures this for DAP at a certain "price point" and due to this requires that the disclaimer "not for aquarium use" when in actuality this is the same high quality silicone I sell for aquarium use on my website. Believe me, it would be easy to tell you that you must buy from me or other Aquarium/Pet Stores, but the truth is I have used this DAP silicone for years and a reputable aquarium manufacturer told me of this many years back. You will note that in my Aquarium Answers post about Aquarium Silicone use that I note that you can get the correct silicone at many hardware stores and you can even see me using DAP in a video and demo picture.

I just wanted to make sure, since it had the same basic disclaimer that the GE Silicone II had - that it shouldn't be submerged, used below the water table, or in aquariums.
It seems that in the case of the DAP, it's just a disclaimer. But like I said, it's the same as the Silicone II and I missed a very important piece of your article the first time I read it:
Also some formulas such as GE Silicon II have a mildew inhibitor (which would be toxic to the fish).

I ended up getting this: The resealable tube like I pictured above was white and would stand out like a sore thumb. The bronze will blend better since I've fixing plants and sandstone-colored ornaments.

I bought some stuff at the hardware store for way less than what the pet store was selling it. It actually has a picture of an angel fish on the package and says "aquarium safe." It also had directions on how to use it on aquariums.
It's DAP Household Adhesive Sealant. 100% silicone. And it's clear.
