I prefer the aluminum

I see no downside of it, even if only pure salt water
. Plus itís not a toxic metal, zinc apparently is.
When in brackish waters, zinc seems to form a whitish layer on it, looks like calcium or something. I suspicion this whitish layer may degrade the performance of the anode, aluminum doesnít form this layer.
