? topping up with inhibitor

[Phill Peck]

How do you then stop magnetite build up?

By not having any in the first place.

How do you know inhibitor stops it.

Isn't it a natural process of oxygen in the water reacting to the steel radiators and other ferrous components? How do you stop that from happening?

Once the oxygen goes out of the system by the aav after the heat exchanger, it should stop in theory assuming your water is neutral ph. Inhibitor is a quick way of getting rid. If you subscribe to that theory. Not all seem to agree.
If your system is badly installed inhibitor won't help you.

As above pretty much install correctly/correct previous defects and remove oxygen= no corrosion.
An aav won’t quite do it though. An rv2 is better and you need to “boil” the system

Boiling would be a bit strong but certainly effective!
See https://en.wikipedia.org/wiki/Degasification for a selection of ways to remove dissolved gas, here relevant is thermal regulation and adding reductant.

The other relevant consideration is that water is chemically h2o, so when you have the real problem of ph acidic or galvanic action, the water is broken into o2 and hydrogen, the o2 causes further corrosion, and the h2 builds up in your system (and can be burnt, see youtube for videos of people burning their bleed air)
In that case the inhibitor can't keep up and quickly gets "used up" binding to the new oxygen.

Good system design
