Odd size filter sock question

[merajm3]

Hi All - Need some advice

So I have a custom acrylic sump that I bought second hand and it has an odd size for filter socks. Diameter is smaller than 4” and too large for 2.75” diameter socks. 4” sock overhang is too high for water level. Looks like it needs a 3 to 3-1/8” diameter sock.

I could try to expand the holes to 4” … but would much rather find a sock to fit (need 3 socks).

Anyone have recommendations on where to find 3” diameter filter socks?

Thanks. I’ll give it a try. This is different from the 2.75” socks I bought because it has a slightly wide outer lip. Still at 2.75” hole but the 3” overhang may work.
