Aquarium Advice Addict
Hello,
I have been working on my rock terrace for a while now using a clear silicone sealant given to me by my husband. I of course asked if it was safe for the fish tank and he said oh yes, it's the same stuff and once it's cured it's fine. ....but now I am feeling nervous about putting it in the tank not knowing 100% that it really IS the same stuff as none of these tubes list the ingredients.
I have read everything on the tube and can not find anything that tells me it is safe for contact with aquariums, or anything useful whatsoever.
It is a Componexx brand RTV-3 Silicon Sealant for industrial applications.
It has a slight vinegar like smell while it cures and then no smell at all.
I have researched the Material Safety Information for several brands of this type of sealant since I could not find anything from this specific mfg. and found them all to be the same as far as reactivity, toxicity etc.
Then I looked up the MSDS for an aquarium safe silicone sealant and it too seemed to be identical, same chemicals were listed under the OSHA safety Hazzard section and all of the other related info was the same as the other sheets.
Can I assume it is safe? Is there a way to test the water after soaking the structure for a few days to tell if it is safe?
If not, can I seal the entire structure to prevent any leaching of harmful chemicals? Would epoxy be the way to go?
Any advice is greatly appreciated.
Most of the work has already been done unfortunately. And I tried to pull it apart to see if I could just start over but it was almost impossible to pull them apart by hand. I would have to start all over which I CAN and will do if I have to but obviously I would like to avoid it.
Any suggestions?
TIA
