I’m treating me quarantine tank for internal parasites. I’ve been treating them for 3weeks to be exact and I still see some signs of white stringy poop. It starts off brown then turns white. I’m wondering if I have a medication resistant strain. Also I have been using the same medicated formula for the full 3 weeks. Does the medication break down over time and maybe that’s why the effectiveness has gone down? Does using garlic guard to make it more palatable cause the white poop as well? Thanks!
