While eating McPukes just now, I had an epiphany.
Where's the harm in having the filter socks after the bubble trap? I know it's not ideal for skimming, but is better than no sock at all.
Thanks again Dave, it was your picture floating in my mind that put it together. Seeing the inlet on the left instead of the back made a world of difference.
Now, instead of one 7" sock, I have room for 3 x 4" socks.
This has really made my day
Can't wait to show everyone when it's done.
