SUMP/REFUGIUM USING BINS?

[Zero]

this bin is proly 30- 40 gallons

so my idea is have my gravity fed pvc pipe going down to my sump bin into container 1 with filter material,
It will then overflow into contain 2 that has another filter media which will flow through foam material and then into the main bin which will have live sand and a ton (10-20lbs maybe) of rubble, my skimmer will also be mounted in the "main" bin.
Skimmer excess water will be dumped into my return bin, which hopfully, will be extremely clean water being pumped back into my tank right above my powerhead.

later on I will add a canister filter outside this bin and most likely have my reactors or what have you aswell with this.
