I have had my tank for 6 months have noticed that a couple of my guppies look like they have got fin rot, so I went to my local aquarium, which they suggested to use tetra medica general tonic. I put the first dose in and has made my water go totally green, does anyone no if this is normal?? I know that I have to carry on the treatment for 5 days so I'm assuming this green colour is going to be here for a while, but for how long???
Thanks
