I clear for about 5 minutes. The water is generally
clear after 2 or so but I keep going a little while

Hypo is 3% solution and I generally fix for around 1
minute. I do notice some sensitizer dissipating at
this point. The hypo is usually room temperature.

How would I acidify the baths?

As for the formula, I'm using Bostick & Sullivan's
kit, so I assume it's a decent brew!

Thanks Matt!
