Cryptic Zone Along with an Algae Scrubber?

[Harry_Y]

I have a 180 gallon tank with a 100 gallon Rubbermaid stock tank in the basement for a sump.

Currently I have a 26 Gallon plastic box in the sump that used to hold the skimmer that I am
planning on using as a Cryptic Zone (since I need the container to sit the scrubber on top of)

I just built an Algae Scrubber into another 26 Gallon plastic
box that that will sit on top of the existing box.

The water flow will flow:
From the Display
...To the Algae Scrubber
......To the Cryptic Zone
.........To the sump
Then pumped back to the display.

Does anyone see any issues with this setup?

I figured best to ask before I get it all put in place.

I'd make the scrubber last, so that pods and algae won't get stuck before making it to the display.

I wish I could, I have a basement sump.

Hopefully the next house (if I move again) will have a room behind the tank.
