First developer time and temp are critical.
So you need a perfect thermometer.
Temper the film and reel to 100 deg before dropping into the prefilled tank.
6 step process give much better color than 3 step, ie combined bleach fix.
Cross contamination of chemicals will drive you crazy and you will never find what is wrong.
So use dedicated bottles. Kodak 6 step kit is best and use it all one shot.
Set up some nice music, it is 40 min long.
Film looks awful until it dries, do no panic.
