Shelf life and replenishment of C41 chemicals

[VPooler]

Hello!

I have source for minilab grade C41 fix and bleach and I was wondering for how long could these be stored, both concentrates and work solutions.
Also, how would one replenish the bleach and for how long could I store that. I don't want to use starter solution every time and I aim to store and use the same solution longer by periodically replenishing it.
Excuse my ignorance, I am new to colour chemistry.

The fix, the bleach, and the stabilizer are all very long-lived will sit on the shelf nearly forever from what I understand.

You should be able to find online the replenishment rates for the specific chemicals that you're buying buying.

I currently have bleach in a half-empty 5l canister, it reads 5ml replenishment per 35mm film so I should be fine for a while. Should decant the remaining concentrate into smaller bottle after mixing up the work solution. It also reads the time 45s @ 38 +/- 3 centigrade.
Oh, and I have heard about aerating the bleach, sooo...I shouldn't top the work solution to the rim of the bottle?
