My biggest nightmare came true! Left my tap water hose on for about 4-5 hours in a 2,500-gallon koi pond. Just came home and found two dead and the rest gasping. I threw in a detoxifier immediately and agitated as much water as I could. I threw in protect from aquascape which helps with their slime coat. I retested the water and chlorine is at zero now. I know the damage is done. Is there anything else I can do to give these guys a chance? I have plenty of aeration going already.
