As far as I understand it's not necessary for film
I just do the ilford method, you can find plenty of people online sharing their test results that it's perfectly good enough.
Plenty of people disagreeing as well but it's a bit like if you believe in climate change or not. That's on you.
Do people use hypo clear when developing film? Trying to cut down on my wash times/water usage.
Also, where can I get a hose to connect the tap end to the tank? What do other people do?
