Metal Goldfish Tank/tub, what can i do to aviod water condition alterations? Options

[Christo7]

Hi i have a very large metal tub sitting outside which im considering using as a temporary tank outside.

I dont know if its even possible to...but can it actually work? is there anything i can do to the inside of it to ensure it doesnt alter water conditions. At the moment its pretty rusty. Are there any experts or experienced people on this?


thanks

i know what u can do!
go to the hardware shop and get some pond liner, and put that down over your rusty tub, then u can fill it with water and not have to worry about the rust. i know alot of people that have done that.
hope that helps and good luck!
