Hi Matt, Thanks for the advice. I refilled the pond on Friday at about 6:00 p.m. I turned the waterfall back on Saturday morning. At about 5:00 p.m. I add a dechlorinator to the pond. It claimed to get rid of all the nasties in my city water. At 7:00 p.m. I released the fish back into the pond. I took the temp of the tub water and the pond water and they were within a degree of being the same temperature. The fish seem to be just fine. Would it be too late to go ahead and dose the pond with Stresscoat? Don't want to aggravate the situation! Myra Amler amler@mindspring.com "Where are we going and why am I in this handbasket?" Unknown
