Matt,

You would be better off saving the 5 liters in a number of smaller
bottles. That way you don't expose all the solution to air every time you
open a bottle and pour off some solution to make your working dilution.

There are many ways to do it. Whatever works for you. I split the 5 liters
into 4 1.5 liter bottles I get mineral water in (I'm trying to be
"correct" here. I do use mineral water bottles if I have them, but the
kids drink more Coke than water, so I use 1.5 liter bottles that used to
have Coke in it). That gives me 4.5 liters. I then have a few smaller
bottles (once again, mineral water or Coke): 500 ml.

When it's time to break open a 1.5 liter bottle, I empty it over into 3
smaller bottles and work out of them. When they're finished I just refill
them (cleaning them out and all of course).

As for working solution. It's a religion.

You'll find times for 1:1 (1 part Xtol 1 part water). You can also use it
straight (don't) or 1:2 or 1:3.

I've settled on 1:2 or 1:3 depending on my patience. You'll have to look
around for the times for starters.

A roll in a stainless steel tank requires 225ml of solution (for me).
Diluting at 1:2 that gives me 75 ml of Xtol and 150 ml of water (1:2).

Some say use distilled water, I don't. I used to but I quit and I haven't
noticed any difference. It all depends on your tap-water locally.

I think this site has Kodak's old recommendations for various dilutions.
Kodak quit publishing them:

choose Xtol). They're not sacred times. But they'll get you started.
