I have a bucket in the garden, and a bag of socks. Swap out twice a week, one of them being a few hours after my water change. I tried no socks but my sump was a mess, water murky and build up of organics made the tank look dirty.
I have read a little and a lot, but not all filter feeders enjoy a micron size lower than a 200 microns. It’s been argued most acropora enjoy <80 microns. Sponges operate on mostly DOC. Bacteria is minute andcgets through fine. Your skimmer still skims with socks right.
It’s really not hard to whip out a few socks into a bucket and add a couple. Like someone else said, they’re cheap, easy and help. My question back is, is this not a hobby? Do we not like to do stuff with our tanks, look after it, tinker? Maybe I’m different.
Regarding the bleach, don’t use too much, run an extra rinse and let them air dry.
I’ve never had an issue with bleach. Occasionally I’ll take them out of the bag and still smell chlorine. I just let them stand out overnight and it fades.
I wouldn’t run without them but each to their own, if what you do fits with your tank method, schedule, etc them more power to you and let’s all have great tanks
