Analog film photography and cameras

Do people use hypo clear when developing film? Trying to cut down on my wash times/water usage.

I do. 2 min soak with it.

Also, where can I get a hose to connect the tap end to the tank? What do other people do?

I have tried both DIRECT to dry after hypo clear and a wash and dry, I could see no diff, then again, I dev, scan and discard negative (frames) that are not worth keeping.

Also, where can I get a hose to connect the tap end to the tank?

There's this one from JOBO -

What do other people do?

I always just used running water and moved things around a lot.

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.
