Certainly sounds more ominous than, "I cleaned a bunch of biological fouling off my fresh-water tank's filter by immersing it in a solution of Clorox & water".
During the effort chronicled in my last post, I totally forgot about checking the filter. I did that today, and sure enough it was partially clogged with bugs/microbes.
Everthing's clean now.
As in the past, a weak solution of Clorox & water will be run through the system before the start of next season's warm-weather camping. But I'm still surprised at what can accumulate on the strainer over the course of one season
