Filter Sock vs Filter Wool

[gordoncheers]

Does anyone have experience in using filter socks in their sump system?
How does it differ from filter wool?

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)

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.

I think I tend to clean the socks more often because it so easy.
With floss I would often forget about it, allowing it to spew excess nitrate back into the system.
