Hi,
I've noticed in photos of darkroom setups that people often have 2 water filters. What are they for? I installed one for particle matter but it is not enough. Everything is fine until it comes to the rinse. i use distilled water for everything except rinsing. I filter the developer and fixer, but when it comes to rinsing, i get these little white specks clinging hard to the film. i remove them manually with my fingers but I think this might scratch the emulsion, I'd rather remove these specks with a filter beforehand, but what could they be? what 2nd filter should I install?
thanks
