there might be some debate over the use of filter socks
i dont know all the ins and outs of the debate but i chose not to use one up until this point in time w/ my reef... wanted the tank to get established and wanted there to be free flow throughout the system for pods etc. now that its established and thriving i believe i am going to start using one - as the detritus seems to accumulate in the sump/fuge areas quite a bit... before i would only use one when cleaning the inside of the tank or during 'turkey baster' sessions when blow off all the debris etc from the live rock - catching it in the sock then removing it.
from what have read
if use a sock they ideally would be changed out everyday to prevent nitrates etc although some may debate the freq they need to be changed... they can be cleaned easily by throwing them in the washing machine w/ no detergent.
if you're doing a reef you might want to remove the bioballs.
i thought this was a joke when you first posted it -
but i know how things can be when first getting started in this hobby - hearing talk about phosphates, reactors, refugiums, nitrates, ozone, ETC ETC ETC... like learning an entirely new language! and will end up w/ a phd by time its all said and done!...
good luck!
