I finally got my 5000 gal pond drained, and cleaned (it was disgusting). Seeing we are on well water, I decided to buy 2000 gals, which has chlorine in it. I have my waterfall going, and 2 other pumps splashing into the water. I have added some well water - which will be added slowly over the next week. How long before the chlorine evaporates from the 2000 gals? I have only added one plant to the pond - the rest need to be repotted and will be added this week. I also have a bottle of beneficial bacteria to add - when should I add that. The goldfish hopefully will be added as soon as the chlorine is gone. There are no stores around me that sell items to measure chlorine. Hope someone can help. Thank you
