Bottom vacuum weir for barebottom reef?

[Maximitsurugi]

This looks like a good enough and simply implemented idea for a barebottom tank. Would do it without the inside piece with the floss and all it’d take is to setup flow for the detritus dead spot to be right next to it.

Any thoughts?

Seen similar stuff for a long time. I’m not sold on it because the small gaps would just grow sponges/feather dusters and such and become much less effective over time. By contrast, a pump pushing along the bottom would suspend the detritus back into the water column for corals to eat or for it to go over the overflow normally and into the sump. Not that it couldn’t work, I’m just not convinced it’s worth the extra effort is all.

Well I’d clean it pretty often. My current barebottom has very low sediment but some particles, although small, just don’t get into the overflow and I’m ripping flow.
I still have that one spot that needs to be vacuumed daily for the tank to look good. Would save me a n extended period vacuuming if the tiny particulate matter were to make its way out.
I’m hand building this new tank. 30 X 24 x 16. I’d do the weir myself. It’s shallow so I don’t wanna slosh water out the tank

By the way if you’re the same @RocketEngineer that guides us with stands etc then OMG, I Love your work. I really appreciate the diagrams etc. Especially since I try to DIY most stuff I do. Youre my go to for building anything stand wise!

Yup, that's me. For some reason, that thread has continued to be popular. I blame the pretty pictures.

If the flow isn't enough to pick that crud up into the water column, I'm curious if a) that one spot might need more flow, or b) that crud is denser than the rest of stuff and might not be picked up anyways.

Just some thoughts.

More dense it seems.
