I have just treated my tank for ich with Mardel's Copper Safe. I went to their web site to try and get answers, but I couldn't. Well, my question is, I removed all the plants and my one ghost shrimp in my tank because the directions told me to. However, they never said when it would be safe to return them. It just says the treatment stays in the tank for a month. I have the shrimp in a tupperware container for the time being , because I have no idea where to leave him. The other problem is I have internal parasites as well, and the box says nothing about using a different treatment at the same time. Does anyone have experience with this sort of thing? If anyone can help, or put me in the right direction (web site or something) I would be greatful
