lol i highly doubt copper embeds itself into the silicone, it may stay on it but i highly highly highly doubt it will be permenently stuck to it, it has a better chance of getting stuck to the glass then the silicone. the rock i can see it as it is pretty porous but the silicone? come on

Ummm...YES. The wife of one of our reef club members works as a lab tech on Wright-Patterson AFB, and she has access to a mass-spec, so she occasionally slides in a few water tests for us. One member was resealing a hospital/QT tank, and saved a piece of the old silicone to check out...... guess what?? There was copper present. I couldn't tell you what the number was, or even what it meant, but she said it was present in a low concentration.... Considering many corals & inverts are intolerant to even a trace of copper, I would be reluctant to take the chance.

take it down a notch good sir, don't let people scare you to much and stress out alot, if she said she put only a little then do what you can to remove it from the system, there are many many many people that use tap water in their marine aquariums and tap water contains Cu in it, dranted the levels may be lower but if you generally use RODI water then there should not be any Cu to be found other then what is added, and the aditive is not a super heavy concentration. there is a certain level of Cu that fish and even inverts can handle, it may cause some stress but get a Cu test kit and add some Cu removers to help suck out as much Cu as possible.

take it slow and steady and don't jump the gun its not worth it to stress out over a single small dose

i find this hard to believe, silicone is not a porous material and very few things will stick to it once its cured even itself. with proper rinsing i can see the silicone being clear of Cu i would be more concerned abotu the glass as it is more porous then the silicone is

i've resealed my aquariums before and filled it with tap water, which has traces of Cu in it had the tank leak test for months upon months, had sand rinsed with tap water and my inverts are perfectly fine, they are actually thriving.

i understand that heavy dosing of Cu can cause issues but don't scare soemone because of a relitivly small single dose. i'm not sayign he won't have issues and i'm not sayign he will, there is only one thing he can do right now to combat the accidental dosing and that is do what he can to remove as much of it from his system as possible

Agreed.... Not trying to be a fear monger, here. In a low single dose, if there's problems, it's far more likely to be with the porous substrate & rock, but heavy metals can settle in quick, and there's the possibility that the tank itself can present problems...

I also agree here.
Copper is lethal to your bacteria at a certain dose. So by keeping an eye on your ammonia and nitrite levels you will see if the dose was strong enough or not. A big water change and carbon filtering and watch. Oh yeah, cross your fingers.

Ok thank you all for your help and input. I did a 35 percent water change with carbon bags in. Added heavy metal removers to the water and all parameters check out. I dont have a coper tester so I will get one tomorrow. Everything in the tank looks fine and is all open. Thank you all again. I will see what happens. How long does it take to generally take before I see negative effects?

never had to dose so i'm only speculating but it shouldn't take to long before you would notice the corals beign stressed out and anemones begin to close up
