40 breeder sump with spinnig chaeto

[CenlaReefer]

I am planning to use a 90 gallon DT with a 40 breeder as the DIY sump. What are some good ideas for design to get the best spin for a large compartment for chaeto?

Interesting question. I'll follow along to see if anyone has good ideas. My chaeto in my standard 3 chamber diy 40b sump never tumbles. But it grows just fine. I used to have a little pump in there which did keep it tumbling but the chaeto kept clogging the pump
