I have an acre pond which was recently cleaned to down to fresh clay. I have placed anchors before it fills as we have always struggled with them, and am hoping to do it correctly this time. The anchors are set and now need chain. Here's my trouble: they have rebar as the "loop" (at my husband's suggestion), but now am reading that I can't mix metals so it sounds as if stainless is out because it will corrode the rebar. I'm more concerned about damaging the anchor because I don't want to drag those out some day. What can I use for chain, cable, anything that won't damage the rebar, and is there swivel to keep the chains from twisting that is preferred?
