Don, where do you find the smaller weaved filter socks for aquariums? I know you can get filters down in micron and below range. I wonder if it would be best to stack them like you do with reverse osmosis carbon. 5 then one micron. To strain the particulates i would think that 200, 100 then maybe 25 to 50. I have only used down to 100.
Is it practical to use a sock below 25 or so?
I wouldnt stack them, that would be a pain. You get them from filterbag.com. Is it practical? That depends on the tank and the owner. My last tank could go three days on a 5 micron. It does take time to get the tank clean enough to use a 5.
Your not going to stick a low micron sock on a new setup with shedding rock and not have it plug very quickly.
