When you use filtration that's dependent on an overflow box for water intake, doesn't that only clean the top and maybe middle of the tank's water? What about the detritus at the bottom of the tank?

That's where good water flow comes in to eliminate dead spots on the tank floor. Also using a gravel vacuum to clean the substrate is useful

Yeah, but it's sitting there and decaying between water changes.
That doesn't happen (usually) with filters that have an intake mid level or near the bottom.
And you can aim a water pump down there to circulate the filth but it's just more equipment and some livestock like calm areas to hang out or rest.

Hi
I've used "purge systems "particularly with large messy fish. Amazing how much debris accumulates even with small tetras ??lolSupposedly the "dangerous " stuff accumulates at the surface so overflow is more efficeint
I use a modified system on an outdoor pool with GF. While it does NOT remove everything at least 50 percent with no help from me!! gary

I have giant Oscars in a 200 gallon that accumulate waste on the bottom no matter how much flow I have, and I have allot. But even so it gets into the sand/gravel as well over time. Before i do a water change I shut down the filters and churn-up all the sand/gravel and suspend as much poo into the water-column as possible, then turn the filters on again (500 GPH overflow-sump and FX5). The filters (mostly FX5) catch 90% of the suspended debris as I also use an attach flexible hose on the FX5 intake chasing the chucks. After the tank is sparking again (30 minutes) I do a 50 % water-change. However when I introduce the new replacement water I again shut down the filters and with a garden sprayer attached to the garden hose I again churn-up the sand/gravel to the bottom of the glass tank everything gets plowed. After top-off I again turn on the filters and the chase the remaining suspended particles. This leaves my tank sand/gravel pristine until the next scheduled 3 month WC/6 month filter service.

A purge system would be ideal for a tank like that The best way I've found is a suspended false bottom . incoming water is forced through the gravel which is then picked up by regular filtration. You'll have to experiment with how much and how often to do it. if you have a good water source. For large fish large gravel worked the best. Will almost eliminate hand labor gary
