Coast to Coast Settling Issue

[CStrickland]

Hi all!
I really like my c2c so far, I think it's doing a very good job of skimming stuff out of the tank. I do find that once the crud makes its way to the overflow it is tending to settle a bit rather than being carried to the sump. I have just been going at it with a toothbrush weekly (when I blow off the rocks prior to vac'ing the sand) to nudge it along before I change my filter sock. I figure if the flow is low enough for it to settle there it probably isn't doing too much to the water quality. I'm not worried about my levels, it's just not something I anticipated. I think that part of the issue is I have a 55 so the back side is relatively long for the amount of water I need to move through the overflow. Like, a 5x overflow on a 40b is not as spread out, I'm seeing it mostly at the far corners.

Was wondering if this an issue others have had, and if so what they do.
Thanks!

I've got a 120, which is the same length for over 2x the volume so I haven't seen it personally, but I suspect you're right - relatively low lateral flow in the overflow.

Short of brushing it out manually, you could take a piece of acrylic and hold it on half of the overflow at time to force more volume over the other half and try flushing the debris towards the siphon that way. You could also take a small pump like a maxi jet with some tubing on it and use that to 'blow' the debris out.

I like that idea about blocking one side, I'll try that.
Thanks doc

Turkey baster?

If it's loose stuff, that should get it moving.

I can baste some of it free, some is a heavier, greasy sort that needs more help once it lands. Trouble is, at the ends of the overflow it kinda settles back down right away, there's very little current in the corners. I'm only getting like 300-350gph and the box is in the middle, so like a foot and a half from the corners. Pouring the top up water in from the corners helps flush some along too.
It's not bugging me that much. Just a bit surprised it's not more common, I don't recall reading about it when I was planning.
