Just dropped by a local pool store, to pickup CYA. It was not my normal pool store, but it was on the way. So I get chatting with the shop owner and he starts talking about how salt pools are now being implicated in heater erosion issues. He says he's just started installing Zinc Anodes in the pump system somewhere to reduce the erosion associated with the salt. Further, he said it would cost me a mere $200.00 to have such a thing installed, including wiring it to the box, on my pool. I do know that my boat motor has a sacrificial anode on it, for use in salt water, and that it's purpose is to prevent erosion of the metal on the motor.
I'd appreciate any input any of you had as to whether this would be good/ bad for the water (as I'm nearly certain that the design principles of the boat anode were not focusing on water quality). Also, does it need to be wired to the electric box? Are they a good idea/ bad idea, not worth it? can the same thing be done by just dropping a hunk of zinc in a skimmer basket?
As always, input is greatly appreciated.
