Do I need to replace anode rod in my water heater

Hi my water heater was installed about 2.5 year ago. I checked the anode rod today, and the core is visible at top, but the rest seems to be ok, so not sure if I should replace it? Pictures attached.

As per this website:

With a water softener or acidic water: every 1-2 years

Replace anode when inspection shows exposed core is visible at top or bottom, or more than 6" of exposed core along length.

I also have water softener in my house.

Thanks.

It looks as if there is still a fair amount of aluminum (or magnesium) on the rod. I would sand off any scale if necessary to get back to bare metal and put it back for another year or two if there is indeed a fair amount of metal left. I think I replaced my rod at the 5 year point when the magnesium was about 80% gone overall. I have a water softener.

Does every heater have one?

I change mine every two years and it looks half as bad as yours. $30 is very insignificant cost to maintain a tank.

Yup.
If you want to extend the life of your tank, it's a good idea to check and change as necessary. Once the rod is gone, your tank starts to rust.

Is it true that wrapping teflon tape around the threads on the anode rod will prevent it from doing its job properly?

Don't know if it's true or not but here's what page 30 of my GSW water heater manual says:
"Use Teflon® tape or an approved pipe sealant on threads
of the new anode rod."
