Copper treatment with macro algae

[Doctorgori]

Are there any risk in re-using my macro algae after treating with copper in the QT ?
I’ve never used copper with macro algae and have no clue if the tissue will leach copper back into the water, or if it even survives the copper dose…

background: I use light and mostly ulva, et in the QT …mostly as a water quality thing, and I’m asking because some of the red macro stuff is worth keeping…I got no issue tossing the ulva or chaeto eitherway

Yes -it will get through the roots and to the plant

I would toss it out, I would be worried inverts or fish may eat it.

that’s what I needed to know…appreciate that

argh…

I didn’t think about that, nor about when/if it dies…

I hate it when I ask a stupid question …Thank you

It's an interesting question - I'm not sure without measuring - its impossible to know. However - you can certainly take cuttings lets say grown in another tank and replace them.

Interesting question, I don’t know. Ionic copper will likely kill most thin walled algae, coppersafe not so much. I don’t know if the algae bioaccumulates copper though.
