Sump & filter socks - 4 or 7 "

[MitchM]

The 150 is a fairly new setup, so I plan on feeding heavier as the system matures. I've been feeding lightly to start.

anyone else running filter socks on a 125 +/- gallon?

If so what size and how many ? heavily stocked ? lots of water turning over ?

My new 300 is going to have 3 - 7" poly mesh sock not the felt type of sock. These are much easier to clean & don't plug up as fast. Also a friend of mine is also running 2 - 7" poly mesh socks on his 300 gal.

If you can just use 1 - 7" sock versus 3 or 4 of the 4" socks it might just be easier to handle.

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....

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
