Weird weir question

[Funkcol]

Howdy y'all. I just bought this new aquarium that has a weir design I'm unfamiliar with. Usually weirs are sealed to the back of tank, but this one is not and has a glass encasement that houses the overflow and return. My question is, should I seal the weir to back of tank? I'm concerned about build-up in between weir and enasement, but I'm also concerned that if I don't seal it, it will diminish the skimming of weir by allowing water in along edges. Pic included for clarity. Any advice would be greatly appreciated.

Yeah my concern would be the exact same. I would glue the weir to the glass encasement

Stick a piece of foam or filter floss around it and have a cryptic zone between the glass and the acrylic.

You suggest this in lieu of sealing the weir, or in addition?

I think if you seal it you will still get some water in it and then you will need to remove the seal to get at any accumulation that slips inside.

The weir will work fine without a seal, just thought that a mechanical barrier might keep the water flowing into the sump for filtration.

it will get water between when the water flows over the teeth it will fill up until it spills over the glass box.

I'd need a better picture it looks like someone made that tank into an overflow tank and that glass box may be able to be deleted and use the abs weir in its place.

also having both doesn’t make much mechanical sense since the glass is the determining water height. the black abs with the teeth is just for looks until the glass overflow box is gone.

I'm assuming with this picture.
