I have had many horses who play in the water. Several of my old herd used to sink their faces in and slosh the water around like kids do in a tub. My 5yo Qh, Buster likes to paw in my current tank.
Since it's now empty, I'd remove it and for the winter, use smaller, rubber tanks, like those made for 30-40 gallons. They are easy to bend and de-ice.
IMHO, electric water heaters are an accident waiting to happen anyway--not going to preach to you, however.
I don't like breaking ice of my 60 gallon tank, and I've frozen 2 steel tanks until they starting leaking. (My last one, 110 gallon steel, is now my baby chick brooder, so hang on to the ones that leak if you might have another purpose for it.)
Another idea--buy some cement blocks and place it on those so it's too tall for your horse to put his leg in it. Good luck, and let us know what you do. =D
