Sump & filter socks - 4 or 7 "

[hfp75]

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.
