Real treasure in SWFOWLR

[Mirek]

I want to make a real treasure chest filled with real gold coins that I
want to put in my swfowlr tank. Anyone know of any negative effects
that might have on my tank inhibitants? couple of small fish with some
inverts. I can imagine some corrosion and damage to the coins but am
not really worried about that . Just the fish and water quality?

thanks
Mirek

As the metals corrode, the metals in the water will undoubtedly
destroy the inhabitants of your tank. You could consider coating the
coins with clear epoxy or silicone......

good thought with the silicine, the coins i have are gold but i still
thought they would corrode in sal****er. You think the silicone will be
ok in the tank?

Pure gold will not corrode in any tank with live fish in.
Most coins probably won't either, unless they are really debased.

most likely silicone is what is holding your tank together so it is just
fine in tanks, just make sure you get 100% silicone without any fancy
additives if you get it from a hardware store.

*Nearly* any metal WILL corrode in water, especially sal****er. Use
nothing metallic in a sal****er tank except the highest quality
stainless steel. Personal experience as well as science backs up my
claim.

Pure silicone is perfectly safe in water, it's what the tanks are
built with.

Oh come on! Unless you fill your tank with hydrofluoric acid there isn't
really much that would be able to corrode gold.

The "chest" would be a different matter, of course.

Ok.
Have you tried gold?
Pure gold is more inert than stainless steel.

Have you ever tried to get enough *pure* gold to make aquarium
decorations? I know there's a lot of money in my tanks, but that's
fricking silly. <g>

Acquiring gold that is pure enough to not contain other metals (ones
that will corrode) could prove both difficult as well as
prohibitively expensive. Nickel, zinc, iron, etc.....

Coinage gold is generally pure enough to be fairly chemically inert.

True, but the OP was explicitely talking about gold coins.
And those are typically almost 100% pure gold.
