As a former diesel mechanic this is something that is common among diesels some more than others due to the kinetic energy formed around cylinder walls especially on inline 6 cyl's. What people fail to realize is when material is removed from one spot is then moved to another. A anode will only allow the process to chew away at that material but the material does not just simply disappear it just gets moved to another area in the coolant system.
The best way is to buy Nitrate additive from the auto parts store. Nitrate can be tested with test strips purchased from the auto store (napa) also. Nitrate basically coats all the internal parts and protects the internals from being eaten by electrolysis by basically creating a shield to be eaten instead of the internal metals themselves. Since nitrate is a chemical compund there is no worry about materials being shifted around. Some say use distilled water yada yada but it really does not matter. What matters is the nitrate levels.
I have personally tested 5 different brands of brand new coolants that I had in my garage all brand new never been open and only 2 of the 5 had nitrate in them and it was to my surprise the cheaper brands.

A sacrificial Anode is not the answer. Yes its better than letting your motor get trashed but just band aid. Nitrate is simple and easy and it belongs in the coolant system.
Hope this helps anyone.

Have you had before and after proof? Inspection of internals of an Engine run on higher concentration of Nitrate vs not? Not challenging, just curious how it compares in actual experience.

Thanks
