What metals are safe for inside of the aquarium

[aquaculture]

I know that gold and titanium are safe, but waht other metals are.

I plan on using a 4 inch stainless steel lag bolt to connect a piece of unsinkable dritfwood to a 6 pound piece of slate.

Would the stainless steel bolt be safe to use or what?

thanks, and please list other metals than the ones mentioned that are fish safe.

this is for freshwater use.

also this wood is from the pacific ocean , but has had salt leached out of it.

If you use stainless steel it will only e safe if you use a high grade. The lower the grade the less nickel and more iron it has in it.

how would i know if it is high grade ,the lag bolt was purchased today costed me $ 3.02 for the one 3/8" x 4 " bolt.

You could use a nylon bolt instead of a steel one

the nylon bolts dont have enough bite and are skinny enough to be snapped like a twig.

once the bolt is in place you can coat it with resin so it can not come in contact with the water.

about the driftwood, i wouldnt worry about it. if you rinsed it well enough, or boiled it, it will be safe. I use salt in my freshwater aquarium anyway (only the recomended dose)

I agree with coating the bolt with something to prevent it from coming in contact with the water. What are you using the bolt for?

Also on a side note holy crap dude what is going on in your avatar? Is it the dark version of Winnie the Pooh?

Any grade of Stainless Steel is fine in a freshwater tank. Most other metals are fine too. And yes, that includes copper too. (Let the flaming begin.)

Things to stay away from: mercury, lead, & arsenic.

I probably won't be checking in for several days, so I may as well explain the copper/metals thing. They won't dissolve at a rate that will ever be harmful to freshwater fish. Your water changes will dillute the metal ions faster than they can dissolve into the water. They won't have a chance to get up to medicinal levels, let alone toxic levels.

If the water is so acidic that the metals dissolve at a detectable rate, then the fish have bigger problems than just metals (they will be dead well before the metals are an issue).

go for V2A or V4A steel.
