I talked to Bona over in the lab section and he pointed out that EO can degrade plastic and suggested that this may have created the gel like substance. The EO content of the gear my have been quite high in which case it likely degraded the filter long before I pushed all 60mg through. Novice mistake.
I wasn't aware that EO itself could cause reactions unto all this occurred. Can it cause sides beyond PIP? I've been dealing with a mild fever for the past few days.
