Default Type of Anode... which do you use?

Hello All,
I keep my boat in the Conn. River. It is fresh water, I ordered Magnesium Anodes last year. Based on my research that seemed to make the most sense. Magnesium make sense to you for my kind of water? They did not seem to erode much.

But that is the point of a sacrificial anode. To corrode / erode so the steel and aluminum don't keeping the electrolytic effect to a minimum..

As far as the best one for your application, I'm sure there is a chart out there which I know I have seen.

Yes, magnesium is the correct type of anode for fresh water. Aluminum or zinc is for brackish and salt water. Neither of these would provide much, if any, protection in fresh water. Magnesium wouldn't last long in salt water. Unless you have a lot of stray electrical current in the water where you dock, your magnesium anodes should probably last for several years.
