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?
I dont think the stainless will corrode the rebar. I think the rebar will corrode the stainless. We use stainless at my work eveyday and never have a problem the the carbon steel (rebar). If the 2 are touching the stainless will start to rust almost immediately. I know its sound weird it should be the other way around. Btw welcome to the forum. Now I could be wrong there are lots of different grades of SS (stainless steel) and carbon steel (CS).
Galvanic corrosion between dissimilar metals is going to happen in water unless you electrically insulate one member from the other. One metal acting as the anode and the other acting as the cathode. The less noble metal will be the anode and corrode.
Can you just go with a heavy ski rope type material or similar, that is ultraviolet light resistant, instead of chain? Non-conductive coating/plating on one member would work but can wear thru if there is going to be relative motion between the surfaces. An after thought...How about a piece of heavy rubber hose, or similar and durable electrical insulator, wrapped around the rebar loop and then attach the chain?

I am anchoring several things. At least 2 toys made from mooring bouys, one is a teeter totter and the other a crow's nest bouy, also a trampoline, and a couple small inflatable rafts.
Thanks for the welcome! I've been busy in my yard and not able to research lately. I think I recall that the rebar will corrode SS, and SS corrodes galvanized...but I could be wrong.
I'm not sure a heavy rope of any kind will last as long as I'm hoping for. Diving or draining aren't appealing to me as long as I can avoid it. I do think I'm going to wrap with a rubber hose as you suggested, as well as using flexi seal on the rebar. A friend mentioned using chrome as a connector, but struggling to find anything. I wonder about airline cable... is that an option?
1st u have 2 screenshot it - then go under switch to full screen reply, then go under file manager then choose your file then add it then, then click done. It takes a few times to get it just try a few times
These are pics from a pond we visit. I have a friend who will make mine. The teeter totter can be used cooperatively, but is much more fun trying to dump each other off by going the other way. You can see in one pic how I'm pretty much submerged but still hanging on, it's a lot of fun.
My friend making them also mentioned ideas of using a bouy and filling with water then allowing it to spin freely, like a basketball in the water and try to stay on it and also a teeter totter for 4. I wondered about putting a platform on one and using it to balance.
When I was a kid there was a water park nearby and they had the teeter totter. They also had a bobber. It was a sphere in the water and a post came up with a area you can stand in and you would rock back and forth. The also had a large padded barrel it was cabled on each end and two people would get on and start rolling the barrel until someone fell off. Ohhh to be a kid again..
These are what we use on the job sites. There might be better options but they will hold up for a very long time. I would put a tack weld or something on the clamps at the bottom. Just so your nuts dont backoff. I was wrong again also they are 1/4.
