A hunk at least the size of a chicken egg. Also get a long piece of copper wire. Connect the wire to the metal egg and to the metal frame of the lift. Be sure that you have a good electrical contact at both ends - either solder the wire in place, or clamp in under a screw or bold of some osrt. Now just let the metal egg dangle in the water and LEAVE IT THERE. This tends to transfer the corrosion effects to the metal egg from whatever it is hooked to. When the zinc/magnesium is eaten away, just replace it with a new piece and you're back in business. This works quite well on boats in salt water, so it should help in your pool. At least, I think so. Bill.

[Remainder of quote deleted] This has the added benefit if dosing your pool water with zinc oxide, so instead of taking those supplemental zinc tablets, you can just drink an ounce or two of pool water each day and save on the cost of vitamins and minerals. Seriously, you don't want that stuff in your pool. The zinc works because of an electro-chemical reaction. It will actually work better if the zinc is in direct contact with the metal you are trying to protect. If you need to prevent the rust, bolt or otherwise attach the zinc to the metal. If you can, put it where you can't see it - like inside the tube for the lift, because oxidized zinc looks really disgusting. Put it where it is least likely to get wet and you can minimize material loss. As long as there is some unoxidized zinc left, it will continue to work, so you should only need to do this once. ----------------------------------------------------------------- MacRae | Friend, that open mouth | Reveals your whole interior spgreg@csd.lerc.nasa.gov | Silly hollow frog! | -Anon. -----------------------------------------------------------------
