I have never worried about distilled water for D-23.
If tap water is dirty, filter through a coffee filter
Thanks, Jim.

Perhaps the question is. What is the reuse duration of D 23?
Ilford PQ at 1/9 is reusable on prints for a while. At 1/19 on film I one shot it, meaning one use and dump.
Rodinal stops working after 20 minutes and is definitely 'one shot'
If a print does not develop we make another, film is one chance

Rainwater is not so "pure".starting rain collection
It is loaded with the dust & aerosols collected in the atmosphere. Which is why the air is so pure after a rainfall.
It is loaded and acidic with atmospheric CO2, which is how limestone is etched away in karstic landscapes.
I am aware
Rain water is still valuable for many uses
Here I now get 46" a year, collecting it will be easy, storage is the problem
Gravity toilet comes to mind, which works even without city water, which often fails here
I also plan to filter it and distill small amounts

Interesting.
What's the logic for needing distilled water (noting that Jim Noel doesn't use distilled water)? I'll admit I use distilled water for mixing powder developers but I do that more out of "an abundance of caution" rather than knowledge.
And, if your water source is not as clean as tap water, would a water filter such as this be helpful? These have been converted to gravity filters so, while slow, no pumping or squeezing.
Ken Lee's page describes D-23 as slower acting than D-76 due to the lack of Hyrdoquinone. But then says "Developing times for D-23 are similar to those of D-76". Is this an inconsistency or am I not giving enough weight to "similar"?
Finally, does sodium sulfite (powder) have a shelf life?
