Anyone got a specific micron size they prefer? I wanna order a bunch off amazon but not sure if i even know the micron size of the ones i use they're all different. Also if you got a bunch of old ones ill prob buy or trade frags for them. I know theyre a pain and clog super fast but over the years im able to to tell the difference in water clarity so i may just build an army of sox so i can just wash em once a week
