Question: Will old broken concrete change my water parameters, and what can or will it do? The flat smooth side will be facing out so no jagged edges will be present to injure fish if they decide to play chicken with it--my biggest concern is maintaining water quality.
It is against the law here to use concrete bricks or slabs on waterways leading in to Lake Ontario .Granite rocks or stones have to be used because of leaching Where erosion has occurred I have used cemment bricks but filled over with clay my PH is a little below 7 . You would have to check what addetives have been added to the cemment . My biggest concern was when the fish were startled they could get a serious scrape so used the clay and one inch stone . Then my mud pond is in my garden so I would not want unsightly cemment as well it makes it nearly impossible for netting fish .
