Water Gardening: Gave up on the natural bottom pond - concrete!, 1 by Analemma

Thanks for the comments. I believe it's just the alkalinity from the lime in the concrete that causes problems. We're letting it sit for as long as it takes to come to neutral, plus we dosed it with a gallon of muriatic acid that we had around. We're not so much planning on expensive fish, too many raccoons around. We'll probably just dump a bunch of feeder goldfish in it for the entertainment of the grandchildren. I sure have been wading in it a lot, though. And Molly the chocolate lab loves it. I love sitting on that big rock (far right) with a drink!
