I made a 1-gallon batch of Microdol-X yesterday in a bucket, then developed a roll of Ilford's HP5-Plus. Examination of the negatives containing blank sky revealed particles based on something adhering to the glossy side of some of the negatives. I had strained the developer through a coffee filter, but the filter broke open at the bottom. A second filter also broke open. Can someone recommend an excellent, fail-proof way to strain/filter liquids? Thanks.
