3 inch filter sock?

[TankYou]

I bought a custom sump a while back, 4 inch filter socks are too wide, I have never been able to find a 3 inch wide sock. Any one know if they exist?

I have never seen it. What brand is the sump?

It’s an older zero edge sump. I think it’s a zr1 model. 36 gallon.

Weird. Their website says their Classic ZS1 uses standard 4" socks. I know some of the All in One tank use proprietary square or oddly shaped socks.

Its probably third or fourth hand by now. may be missing a filter sock adapter mount that goes below the hole I am trying to stuff it thru, that’s all I can think of. It’s an older version it seems. Can’t find a good pic online of it. When I try to place the sock in the top opening, it’s not going to happen.

I'd just call them and ask.

That I will do, thanks
