Filter Sock Question

[lastlight]

I rinse mine by hand as well as I can in the sink but they are certainly never white or new looking after I'm done. I rotate two socks. Is there any difference in washing them with bleach in the washer besides how clean/how much longer they'll last? Do I have nitrates jammed in the sock if I don't bleach it?

I love a cleaner water column and hate cleaning my socks. I wonder how much of what gets stuck in the sock could instead be skimmed out? I imagine that'd be better since it can't rot away in the water and release nutrients. Trouble is the clear water is nice to have.
