copper question

[michika]

I've always heard and practiced the belief that copper is absorbed into the silicone. I've always stripped out the silicone on second hand tanks just in case they've had copper in them before.

I treated my large bowfront with copper when it was a fish only. Or maybe it was Cupramine, is that different? Anyway, I used a neutralizer of some kind. The tank was a successful reef tank, so it obviously worked. Twelve years ago though, so no can remember what it was called.....

Me too. I just use an exacto blade and trim it out, then reapply the silicone. I've only done this on sumps though, not displays. Not that that matters much I would think.
