I am going to say I am a very firm believer in filter socks.
From what people in the industry have told me filter socks are intended to be used for 1-2 days then replaced with a clean sock. The reason for this is they are mechanically filtering out larger loads of waste (100 micron) then sponges etc. You remove the waste filled sock before Nitrates etc start to emit from the trapped rotting waste.
To make it less of a hassle for myself I have 10 or more socks so I only have to wash them once every 2 weeks with turning them all inside out and rinsing them with Prime it takes me about 5 minutes worth of work.
Since changing to a sock system my skimmer works a tenth as hard as it did before. I have zero Nitrates etc. I have added more live stock to my system with out waste build up. And eliminated the pest algae. I also have no build up of waste residue on my sump bottom and they system runs with a lot less noise.
So that’s how things have been going with my socks. Seems to work for me but I am not you.
