Anode compatibility

Is there an adverse effect of adding say an aluminum anode to a tank that already has a magnesium anode to it? do they "fight"? I am thinking of offering it to customers to add life to their tanks when I install them new. ty,kpc

    Always best...

    ... to keep anodes the same metal in a tank.  I like magnesium for most things.  If different metals are used, say aluminum and magnesium, the Mg will get used up faster protecting the Al anode. 

    By the way, adding a second rod to your client's tanks is doing them a real favor!
