Want to really flush out that crud......forget that wand.
Have to stick it thru hole to use and that partially blocks the drain hole
Wand is OK to rinse inside of tank walls cause you can point it up and sideways.
Power flush it....
With anode rod out stand back and turn water supply ON and let it blast out the drain hole
Inlet diffuser points downward so the water pressure will stir up the crud on bottom of tank and force it out the drain
Suburban OEM anode rod is magnesium because it does provide good protection and will dissolve quicker.
But it can interact with microbes in the water source and stink.....sulfur smell
Aluminum is an optional anode rod but does not dissolve as quickly hence not as good protection and can be harder to remove due to calcium build up on the aluminum....can even result in 'gel' like substance
Aluminum hydroxide=====result of the minerals in the water reacting with the aluminum anode rod
The gel is not harmful..water soluble just drain/flush more frequently
