    I pulled out a bottle of ink the other day, and the plastic cap was bowed up as if it were under pressure. Sure enough, when I opened it, it made a hissing sound like a tiny beer can being opened. It looked fine, smelled fine... I threw it away. I took the pressurization as a sign of some kind of bacterial activity.

    Once SITB has set in, that almost certainly means solution chemistry has changed. The organisms responsible have been eating the dye, surfactant or other ink component.

    Treatment may kill the organisms but still leave you with an altered/unusable ink.

    Worse, treatment may kill the fruiting bodies, but leave residual spores that can stage a comeback and second infestation once biocide levels drop due to evaporation, oxidation or other pathways.
