Hi! I recently inherited three older koi fish and their pond. It's a ~1200 gallon in ground pound. One of the fish has a huge ulcer (I think, I can try to get a photo) and I bought Koi Pharma Koi Defender Pathogenic Bacterial Control to help treat it. But I misread the instructions and used 4 tablespoons instead of 4 teaspoons. How badly did I fuck up? Should I take the fish out or try to replace the water? The pond has an overflow thing so if I leave the hose running the extra water will channel out. Thank you!

EDIT: I spoke to a Koi Pharma rep and they said it was fine because it's just bacteria and not actually medication.
