Filter Sock vs Filter Wool

  • We are currently upgrading MFK. thanks! -neo
I have used both, but started using filter socks in more sumps for about 20 years.

I have a routine, and use 3 socks for each outflow pipe.
While one is filtering, one is soaking in bleach (to clean it out), and one is drying out waiting to be rotated into service.
I like to clean/rotate them every couple days
The reality is both floss and socks do the same thing, so its just about what fits into your maintenance style.
It may also be about cost, socks run about $6 each retail price on-line.
Some people clean them in a washing machine (instead of with bleach) some hose them down. But I find just tossing them in bleach allows them to last longer, (not get beat up as fast)
Below socks during a water change, in my DIY barrel sump

which one do you clean out more often?
cause i'm currently using filter wool in my 400 gallon and i just replace the dirty wool with clean ones weekly.

Filter socks and filter wool serve similar purposes in a sump system, but they differ in efficiency and maintenance. Filter socks are designed to capture larger debris and require regular cleaning to maintain optimal flow, making them ideal for more thorough filtration. In contrast, filter wool is often used for finer particles but can clog up faster and may need more frequent replacement.

I’m doing diy sump and plan on both filter sock and filter floss(poly-fil),will a regular cotton sock work in place of store bought filter sock?
 
My 750gal has four 7" filter socks while my 450gal and 180gal have drip pans.

1. With the drip pans you can layer various density media to your liking, including filter wool vs filter socks which can be different density; ex/ I run two 200 micron socks and two 100 micron socks (catches finer waste) in my sump .
2. Filter socks in my sump fit the housings very snugly (no waste can escape from going through the socks) vs drip pan where filter wool/other media goes only where you put it.
3. Maintenance: in my sumps, replacing filter socks is much quicker & easier than replacing the drip pan media.

I much prefer my sump that uses filter socks.

If the sump has a standard filter sock compartment then you would need to buy the correct size aquarium filter socks to fit the housing there. But I suppose it depends on if your diy sump is setup for these filter socks or cotton men's socks, pillow cases, etc. You get the idea.
