Hello all! New member here looking to help out wherever I can and gain knowledge. As I'm reading through the posts, I noticed people mentioning using copper sulfate. I had no idea that copper sulfate was used in the plumbing industry! Anyway, I have well over 200lbs (probably more so 220-225lbs) of copper sulfate if anyone would like some. I have no use for it and would like to get rid of it. I'm not sure if selling is allowed or not on the forum. I tried to see if there are any rules against it on the forum and didn't find anything, but if I'm overstepping or I'm in the wrong then please let me know! Hope everyone is having a good weekend!
