In general how quickly would y'all say filter socks clog. I've seen a lot of references to changing them multiple times a week and I was wondering if this is because they are clogged or more so for removing organics? I am in the process of designing my sump which will be for a freshwater planted tank where organics export isn't as important. Since changing filter socks isn't every few days isn't practical for me at this point I'd like to understand how quickly they clog necessitating a change so I can decide if I'll be using filter socks or not.
