4" filter socks not exactly the same size?

[Gobi-Wan]

I made my own sump from a 40 breeder and cut holes for filter socks based on the original set I had. The original set has about 1/4" of wiggle room in the holes. When i tried finding replacements, they are also clearly 4" filter socks... but can't quite be wedged into the holes. Apparently there is some discrepancy in filter sock sizes... has anyone noticed this and maybe could recommend brands that fit a little smaller?

Eshopps, waterbox, Red sea all seem to run around the same size and a bit smaller than others.... There may be others as well.

Neat concept. Have you considered making 2" size?

I measured and the bores are 3-1/2" so that would be perfect. do they use the same filter elements as the 3-3/4's?

Sorry, we don't have plans for a 2" Reef Diaper at this time.

Yes, the 3-1/2 flanges use the same elements as the standard 3-3/4" Reef Diaper.
