Hi! I have a ramshorn snail population in my tank, and I cannot, for the life of me, convince my mom that the snails are good. My question is, if I dosed my tank with seachem cupramine copper, would I
A. Have to remove my plants?
B. How long would I have to wait to get otto catfish. I would filter with carbon as well.

sorry if these are stupid questions, I just want to know so I can make sure everything lives after, and wasgetting really mixed reviews from google
