Fill it with plain water and if there are no leaks you never touch it again.

My boiler has the original fill from 1995 and it still is clean and clear

as the day it was installed. The waters oxygen content goes down fast

after installing and if you never add water it will stay that way.

That's the beauty of a hot water system (even though I love steam and big radiators). Once you fill it, heat it and purge the air, you'll never have to worry about it as long as you have no leaks or a failed expansion tank that continuously causes the relief valve to drool whenever the boiler heats up and the auto-fill valve to refill it when it cools back down. That constant supply of oxygen in the water can eat things up pretty quick.

Steam systems (particularly the one-pipe, non vacuum type) suck in air thru the vents every time the boiler cools down and the steam condenses, only to have to purge it all back out on the next call for heat. Boiler treatments to reduce corrosion are much more helpful, as well as keeping the boiler clean to minimize foaming and other nasties that inhibit getting good, dry steam.
