Hot Water System sacrificial anodes

I installed and assembled my solar 30 evacuated tube HWS about 8 years ago, so it is about time to inspect the sacrificial anode (which is Magnesium metal). My tank is stainless steel and has only had rainwater in it, which is slightly acidic (pH <6), but with minimal hardness. It will be interesting to see how much the anode has corroded.
