Yeah, I've read that... that's why I got a sponge filter. It can be a spare filter for a fry, quarantine or hospital tank, as well as providing some extra circulation for my plants.
My thinking was: If I need to pull it from my main tank for some reason, my plants will have to just get on without it. This way I always have a seeded filter available to put into my emergency tank whenever I need it. That should greatly help my with a sick fish, or with getting new stock. I can just cycle up the sponge filter a bit before hand and be go to go in a few days for more fish, meanwhile the drop off shouldn't be much in my main filter in terms of mini-cycling that tank in the process.
Does that make sense?
