Hey guys, dosed 4ml of dino x so my 30g tank to help with my dino issue. Two hours in I shine my light to see if there is any effect and see my yellow tang and firefish dead and one of my clowns breathing heavy. I took all my fish out (in a bucket with air stone) and running a lot of carbon. I've done my research on this product and I'm confused to why this would happen. Please let me know what your thoughts are.
