Sump & filter socks - 4 or 7 "

[reeferfulton]

I run one 4" filter sock on my 110g . I change it every day and a half

I would like to redesign my sump to accomadate a 3 sock system.. I hate haveing to slip the sock under my return pipe..

I have a 180g and just switch over to filter socks from floss last week, I ended up going with one 7" sock for both overflow lines (limited space in sump) been changing it out every two days, so far so good, super easy to swap out! Ps Vertex makes really nice acrylic holders good price too

your 7" when you change it is it really dirty???

and is your 180 light med heavy stock?

If you do some math ...
I'm no math whiz, but the last time I checked, one 7" sock is equal to 3 x 4" socks, give or take

Yes I think it's +\- 3:1 generally but the space for a 7" is more than a 4" so my question is if 2x,3x,4x of the 4" is enough for a 125g, not simpler....

Yes it would be enough so if you want to go with 4" try to find the poly mesh socks versus the felt as they dont clog up as fast, easier to clean and still do the same job as the felt.

I'm running two 7" socks on a heavily stocked 180. I have a 6' sump so I have plenty of space.

My tank is med-heavily stocked, I'd say it's fairly dirty when I change it out pretty brown in colour but not to the point that the sock is overflowing
