If I had 5 or 6 of them I might change them out every few days. Then toss the rest in the wash all at once, however washing one at a time I really feel like I'm wasting water, and I don't feel like making some fancy plumbing system to drain to the back yard... though I should.. .*laugh*
Way I figure it, all the crap I see in them is better to be in the filter sock than in the tank, because that crap will get washed out.. and while it might be "making nitrates" (or whatever nitrate factor buzz terms they use today), it would still be doing that if it was sitting at the bottom of my sump until the next time I manage to clean it out.
